## Class SVNRepository

- java.lang.Object
- - org.tmatesoft.svn.core.io.SVNRepository

-     public abstract class SVNRepository
      extends java.lang.Object

  The abstract class SVNRepository provides an interface for protocol specific drivers used for direct working with a Subversion repository. SVNRepository joins all low-level API methods needed for repository access operations.

  In particular this low-level protocol driver is used by the high-level API (represented by the org.tmatesoft.svn.core.wc package) when an access to a repository is needed.

  It is important to say that before using the library it must be configured according to implimentations to be used. That is if a repository is assumed to be accessed either via the WebDAV protocol (`http://` or `https://`), or a custom svn one (`svn://` or `svn+ssh://`) or immediately on the local machine (`file:///`) a user must initialize the library in a proper way:

       //import neccessary classes
       import org.tmatesoft.svn.core.internal.io.fs.FSRepositoryFactory;
       import org.tmatesoft.svn.core.internal.io.dav.DAVRepositoryFactory;
       import org.tmatesoft.svn.core.internal.io.svn.SVNRepositoryFactoryImpl;
       import org.tmatesoft.svn.core.SVNURL;
       import org.tmatesoft.svn.core.io.SVNRepository;
       import org.tmatesoft.svn.core.io.SVNRepositoryFactory;
       import import org.tmatesoft.svn.core.wc.SVNWCUtil;
       import import org.tmatesoft.svn.core.SVNException;
       ...

       //Set up connection protocols support:
       //http:// and https://
       DAVRepositoryFactory.setup();
       //svn://, svn+xxx:// (svn+ssh:// in particular)
       SVNRepositoryFactoryImpl.setup();
       //file:///
       FSRepositoryFactory.setup();

  `svn+xxx://` can be any tunnel scheme for tunneled working with a repository. `xxx` URL scheme is looked up in the section `tunnels` of the standard Subversion `config` file.

  So, only after these setup steps the client can create http | svn | file protocol implementations of the `SVNRepository` abstract class to access the repository.

  This is a general way how a user creates an SVNRepository driver object:

       String url="http://svn.collab.net/svn/trunk";
       String name="my name";
       String password="my password";
       repository = null;
       try {
           repository = SVNRepositoryFactory.create(SVNURL.parseURIDecoded(url));
           ISVNAuthenticationManager authManager =
                        SVNWCUtil.createDefaultAuthenticationManager(name, password);
           repository.setAuthenticationManager(authManager);
           ...
       } catch (SVNException e){
           e.printStackTrace();
           System.exit(1);
       }
       //work with the repository
       ...

  SVNRepository objects are not thread-safe, we're strongly recommend you not to use one SVNRepository object from within multiple threads.

  Also methods of SVNRepository objects are not reenterable - that is, you can not call operation methods of an SVNRepository driver neither from within those handlers that are passed to some of the driver's methods, nor during committing with the help of a commit editor (until the editor's `closeEdit()` method is called).

  To authenticate a user over network SVNRepository drivers use ISVNAuthenticationManager auth drivers.

  - ### Method Detail

    - #### getLocation

          public SVNURL getLocation()

      Returns the repository location to which this object is set. It may be the location that was used to create this object (see `SVNRepositoryFactory.create(SVNURL)`), or the recent one the object was set to.
      Returns:
        a repository location set for this driver
      See Also:
        `setLocation(SVNURL, boolean)`

    - #### setLocation

          public void setLocation​(SVNURL url,
                                  boolean forceReconnect)
                           throws SVNException

      Sets a new repository location for this object. The ability to reset an old repository location to a new one (to switch the working location) lets a developer to use the same SVNRepository object instead of creating a new object per each repository location. This advantage gives memory & coding efforts economy.

      But you can not specify a new repository location url with a protocol different from the one used for the previous (essentially, the current) repository location, since SVNRepository objects are protocol dependent.

      If a new `url` is located within the same repository, this object just switches to that `url` not closing the current session (i.e. not calling `closeSession()`).

      If either a new `url` refers to the same host (including a port number), or refers to an absolutely different host, or this object has got no repository root location cached (hasn't ever accessed a repository yet), or `forceReconnect` is true, then the current session is closed, cached repository credentials (UUID and repository root directory location ) are reset and this object is switched to a new repository location.

      Parameters:
        `url` - a new repository location url
        `forceReconnect` - if true then forces to close the current session, resets the cached repository credentials and switches this object to a new location (doesn't matter whether it's on the same host or not)
      Throws:
        `SVNException` - if the old url and a new one has got different protocols

    - #### getRepositoryUUID

          public java.lang.String getRepositoryUUID()

      Deprecated.
      use `getRepositoryUUID(boolean)` instead
      Returns:
        the UUID of a repository

    - #### getRepositoryUUID

          public java.lang.String getRepositoryUUID​(boolean forceConnection)
                                             throws SVNException

      Gets the Universal Unique IDentifier (UUID) of the repository this driver is created for.
      Parameters:
        `forceConnection` - if true then forces this driver to test a connection - try to access a repository
      Returns:
        the UUID of a repository
      Throws:
        `SVNException` - in case the repository could not be connected
        `SVNAuthenticationException` - in case of authentication problems

    - #### getRepositoryRoot

          public SVNURL getRepositoryRoot()

      Deprecated.
      use #getRepositoryRoot(boolean) instead
      Returns:
        the repository root directory location url
      See Also:
        `getRepositoryRoot(boolean)`

    - #### getRepositoryRoot

          public SVNURL getRepositoryRoot​(boolean forceConnection)
                                   throws SVNException

      Gets a repository's root directory location. If this driver object is switched to a different repository location during runtime (probably to an absolutely different repository, see `setLocation()`), the root directory location may be changed. This method may need to establish connection with the repository if the information on the repository's root location has not been received yet from the repository.
      Parameters:
        `forceConnection` - if true then forces this driver to test a connection - try to access a repository
      Returns:
        the repository root directory location url
      Throws:
        `SVNException` - in case the repository could not be connected
        `SVNAuthenticationException` - in case of authentication problems
      See Also:
        `testConnection()`

    - #### setAuthenticationManager

          public void setAuthenticationManager​(ISVNAuthenticationManager authManager)

      Sets an authentication driver for this object. The auth driver may be implemented to retrieve cached credentials, to prompt a user for credentials or something else (actually, this is up to an implementor). Also there's a default implementation - see the `SVNWCUtil` class for more details.
      Parameters:
        `authManager` - an authentication driver to provide user credentials
      See Also:
        `getAuthenticationManager()`

    - #### getAuthenticationManager

          public ISVNAuthenticationManager getAuthenticationManager()

      Returns the authentication driver registered for this object.
      Returns:
        an authentication driver that is used by this object to authenticate a user over network

    - #### setTunnelProvider

          public void setTunnelProvider​(ISVNTunnelProvider tunnelProvider)

      Sets a tunnel provider. Actually relevant only to `svn+xxx://` scheme cases. The provider is responsible for matching `xxx` to the tunnel command string.

      If one would like to have a standard Subversion behaviour (when tunnel commands are fetched from the `config` file beneath the section named `tunnels`), he should provide a default provider (default implementation of the `ISVNOptions` interface). Refer to `SVNWCUtil` class for more details on how to get a default options driver.

      Parameters:
        `tunnelProvider` - a tunnel provider
      See Also:
        `getTunnelProvider()`

    - #### getTunnelProvider

          public ISVNTunnelProvider getTunnelProvider()

      Returns a tunnel provider.
      Returns:
        a tunnel provider
      See Also:
        `setTunnelProvider(ISVNTunnelProvider)`

    - #### setCanceller

          public void setCanceller​(ISVNCanceller canceller)

      Sets a canceller to this object.
      Parameters:
        `canceller` - canceller object
      Since:
        1.2.0

    - #### getCanceller

          public ISVNCanceller getCanceller()

      Returns the canceller, stored in this object.
      Returns:
        canceller object
      Since:
        1.2.0

    - #### setRepositoryCredentials

          protected void setRepositoryCredentials​(java.lang.String uuid,
                                                  SVNURL rootURL)

      Caches identification parameters (UUID, rood directory location) of the repository with which this driver is working.

                               throws SVNException

      Retrieves interesting file revisions for the specified file.

      A file revision is represented by an SVNFileRevision object. Each file revision is handled by the file revision handler provided. Only those revisions will be retrieved in which the file was changed. The iteration will begin at the first such revision starting from the `startRevision` and so on - up to the `endRevision`. If the method succeeds, the provided `handler` will have been invoked at least once.

      For the first interesting revision the file contents will be provided to the `handler` as a text delta against an empty file. For the following revisions, the delta will be against the fulltext contents of the previous revision.

      The `path` arg can be both relative to the location of this driver and absolute to the repository root (starts with `"/"`).

      Retrieves interesting file revisions for the specified file with possibility to include merged revisions.

      A file revision is represented by an SVNFileRevision object. Each file revision is handled by the file revision handler provided. The iteration will begin at the first such revision starting from the `startRevision` and so on - up to the `endRevision`.

      Checks that this object is connected to a mergeinfo capable repository.

      If the repository that this object is used to access to does not support merge-tracking, an `SVNException` is thrown with the error code `SVNErrorCode.UNSUPPORTED_FEATURE`.

      `pathOrURL` is used only in an error message. If `pathOrURL` is null, it defaults to the `location` of this object.
      Parameters:
        `pathOrURL` - path or URl string for an error message
      Throws:

                   throws SVNException

      Traverses revisions history. In other words, collects per revision information that includes the revision number, author, datestamp, log message and maybe a list of changed paths (optional). For each revision this information is represented by an SVNLogEntry object. Such objects are passed to the provided `handler`.

      This method invokes `handler` on each log entry from `startRevision` to `endRevision`. `startRevision` may be greater or less than `endRevision`; this just controls whether the log messages are processed in descending or ascending revision number order.

      If `startRevision` or `endRevision` is invalid, it defaults to the youngest.

      If `targetPaths` has one or more elements, then only those revisions are processed in which at least one of `targetPaths` was changed (i.e., if a file text or properties changed; if dir properties changed or an entry was added or deleted). Each path is relative to the repository location that this object is set to.

      If `changedPath` is true, then each SVNLogEntry passed to the handler will contain info about all paths changed in that revision it represents. To get them call `SVNLogEntry.getChangedPaths()` that returns a map, which keys are the changed paths and the values are SVNLogEntryPath objects. If `changedPath` is false, changed paths info will not be provided.

      If `strictNode` is true, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

      Target paths can be both relative to the location of this driver and absolute to the repository root (starts with `"/"`).

      NOTE: you may not invoke methods of this SVNRepository object from within the provided `handler`.

      Parameters:
        `targetPaths` - paths that mean only those revisions at which they were changed
        `startRevision` - a revision to start from
        `endRevision` - a revision to end at
        `changedPath` - if true then revision information will also include all changed paths per revision, otherwise not
        `strictNode` - if true then copy history (if any) is not to be traversed
        `handler` - a caller's handler that will be dispatched log entry objects
      Returns:
        the number of revisions traversed
      Throws:

                          ISVNLogEntryHandler handler)
                   throws SVNException

      Invokes `handler` on each log message from `startRevision` to `endRevision`. `startRevision` may be greater or less than `endRevision`; this just controls whether the log messages are processed in descending or ascending revision number order.

      If `startRevision` or `endRevision` is invalid (`<0`), it defaults to youngest.

      If `targetPaths` is non-null and has one or more elements, then shows only revisions in which at least one of `targetPaths` was changed (i.e., if file, text or props changed; if dir, props changed or an entry was added or deleted). Each path may be either absolut (starts with '/') or relative to this object's `location`.

      If `limit` is non-zero only invokes `handler` on the first `limit` logs.

      If `discoverChangedPaths` is set, then each call to `handler` passes an `SVNLogEntry` object with non-empty `changed paths map`; the hash's keys are all the paths committed in that revision. Otherwise, each call to `handler` passes null for changed paths.

      If `strictNodeHistory` is set, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

      If `includeMergedRevisions` is set, log information for revisions which have been merged to `targetPahts` will also be returned.

      Refer to `SVNLogEntry.hasChildren()` for additional information on how to handle mergeinfo information during a log operation.

      If `revisionProperties` is null, retrieves all revprops; else, retrieves only the revprops named in the array (i.e. retrieves none if the array is empty).

      If any invocation of `handler` throws an exception, then throws that exception immediately and without wrapping it.

      Note: the caller may not invoke any repository access operations using from within `handler`.

      Note: if `targetPahts` is null or empty, the result depends on the server. Pre-1.5 servers will send nothing; 1.5 servers will effectively perform the log operation on the root of the repository. This behavior may be changed in the future to ensure consistency across all pedigrees of server.

      Note: pre-1.5 servers do not support custom revision properties retrieval; if `revisionProperties` is null or contains a revision property other than `SVNRevisionProperty.AUTHOR`, `SVNRevisionProperty.DATE`, `SVNRevisionProperty.LOG`, an exception with the `SVNErrorCode.RA_NOT_IMPLEMENTED` error code is thrown.
      Parameters:
        `targetPaths` - paths that mean only those revisions at which they were changed
        `startRevision` - a revision to start from
        `endRevision` - a revision to end at
        `discoverChangedPaths` - if true then revision information will also include all changed paths per revision, otherwise not
        `strictNodeHistory` - if true then copy history (if any) is not to be traversed
        `limit` - the maximum number of log entries to process
        `includeMergedRevisions` - whether mergeinfo information should be taken into account or not
        `revisionProperties` - revision properties to fetch with log entries
        `handler` - a caller's handler that will be dispatched log entry objects
      Returns:
        the number of revisions traversed
      Throws:
        `SVNException` - in the following cases:
        exception with `SVNErrorCode.FS_NO_SUCH_REVISION` error code - if `startRevision` or `endRevision` is a non-existent revision
        exception with `SVNErrorCode.RA_NOT_IMPLEMENTED` error code - in case of a pre-1.5 server and custom revision properties requested

                           throws SVNException

      Gets entry locations in time. The location of an entry in a repository may change from revision to revision. This method allows to trace entry locations in different revisions.

      For each interesting revision (taken from `revisions`) an entry location is represented by an SVNLocationEntry object which is passed to the provided `handler`. Each SVNLocationEntry object represents a repository path in a definite revision.

      The `path` arg can be both relative to the location of this driver and absolute to the repository root (starts with `"/"`).

      NOTES:

      - you may not invoke methods of this SVNRepository object from within the provided `handler`
      - this functionality is not available in pre-1.1 servers
      Parameters:
        `path` - an item's path
        `pegRevision` - a revision in which `path` is first looked up
        `revisions` - an array of numbers of interesting revisions in which locations are looked up. If `path` doesn't exist in an interesting revision, that revision will be ignored.
        `handler` - a location entry handler that will handle all found entry locations
      Returns:
        the number of the entry locations found
      Throws:
        `SVNException` - in the following cases:
        - `path` not found in the specified `pegRevision`
        - `pegRevision` is not valid
        - a failure occured while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

                                   throws SVNException

      Calls `handler` for each segment in the location history of `path` in `pegRevision`, working backwards in time from `startRevision` to `endRevision`.

      `endRevision` may be invalid (`<0`) to indicate that you want to trace the history of the object to its origin.

      `startRevision` may be invalid to indicate "the HEAD revision". Otherwise, `startRevision` must be younger than `endRevision` (unless `endRevision` is invalid).

      `pegRevision` may be invalid to indicate "the HEAD revision", and must evaluate to be at least as young as `startRevision`.
      Parameters:
        `path` - repository path
        `pegRevision` - revision in which `path` is valid
        `startRevision` - revision range start
        `endRevision` - revision range end
        `handler` - caller's segment handler implementation
      Returns:
        number of revisions covered by all segments found

      Calls `handler` for each segment in the location history of `path` in `pegRevision`, working backwards in time from `startRevision` to `endRevision`.

      The same as `getLocationSegments(String, long, long, long, ISVNLocationSegmentHandler)` except for this method returns a list of all the segments fetched for `path`. The list will be sorted into an ascenging order (segments with greater start revisions will be placed in the head of the list).
      Parameters:
        `path` - repository path
        `pegRevision` - revision in which `path` is valid

                                                throws SVNException

      Retrieves and returns interesting file revisions for the specified file.

      A file revision is represented by an SVNFileRevision object. Only those revisions will be retrieved in which the file was changed. The iteration will begin at the first such revision starting from the `startRevision` and so on - up to the `endRevision`.

      The `path` arg can be both relative to the location of this driver and absolute to the repository root (starts with `"/"`).

      NOTE: this functionality is not available in pre-1.1 servers

      Parameters:
        `path` - a file path
        `revisions` - if not null this collection will receive all the fetched file revisions
        `sRevision` - a revision to start from
        `eRevision` - a revision to stop at
      Returns:

                                   throws SVNException

      Traverses revisions history and returns a collection of log entries. In other words, collects per revision information that includes the revision number, author, datestamp, log message and maybe a list of changed paths (optional). For each revision this information is represented by an SVNLogEntry. object.

      `startRevision` may be greater or less than `endRevision`; this just controls whether the log messages are processed in descending or ascending revision number order.

      If `startRevision` or `endRevision` is invalid, it defaults to the youngest.

      If `targetPaths` has one or more elements, then only those revisions are processed in which at least one of `targetPaths` was changed (i.e., if a file text or properties changed; if dir properties changed or an entry was added or deleted). Each path is relative to the repository location that this object is set to.

      If `changedPath` is true, then each SVNLogEntry object is supplied with info about all paths changed in that revision it represents. To get them call `SVNLogEntry.getChangedPaths()` that returns a map, which keys are the changed paths and the mappings are SVNLogEntryPath objects. If `changedPath` is false, changed paths info will not be provided.

      If `strictNode` is true, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

      Target paths can be both relative to the location of this driver and absolute to the repository root (starts with `"/"`).

      Parameters:
        `targetPaths` - paths that mean only those revisions at which they were changed
        `entries` - if not null then this collection will receive log entries
        `startRevision` - a revision to start from
        `endRevision` - a revision to end at
        `changedPath` - if true then revision information will also include all changed paths per revision, otherwise not
        `strictNode` - if true then copy history (if any) is not to be traversed
      Returns:
        a collection with log entries
      Throws:

      Calculates the differences between two items.

      `target` is the name (one-level path component) of an entry that will restrict the scope of the diff operation to this entry. In other words `target` is a child entry of the directory represented by the repository location to which this object is set. For example, if we have something like `"/dirA/dirB"` in a repository, then this object's repository location may be set to `"svn://host:port/path/to/repos/dirA"`, and `target` may be `"dirB"`.

      If `target` is null or empty (`""`) then the scope of the diff operation is the repository location to which this object is set.

      The `reporter` is used to describe the state of the target item(s) (i.e. items' revision numbers). All the paths described by the `reporter` should be relative to the repository location to which this object is set.

      After that the `editor` is used to carry out all the work on evaluating differences against `url`. This `editor` contains knowledge of where the change will begin (when `ISVNEditor.openRoot()` is called).

      If `ignoreAncestry` is false then the ancestry of the paths being diffed is taken into consideration - they are treated as related. In this case, for example, if calculating differences between two files with identical contents but different ancestry, the entire contents of the target file is considered as having been removed and added again.

      If `ignoreAncestry` is true then the two paths are merely compared ignoring the ancestry.

      NOTE: you may not invoke methods of this SVNRepository object from within the provided `reporter` and `editor`.

      This method is analogous to `diff(url, targetRevision, revision, target, ignoreAncestry, SVNDepth.fromRecurse(recursive), getContents, reporter, editor)`.
      Parameters:
        `url` - a repository location of the entry against which differences are calculated
        `targetRevision` - a revision number of the entry located at the specified `url`; defaults to the latest revision (HEAD) if this arg is invalid
        `revision` - a revision number of the repository location to which this driver object is set
        `target` - a target entry name (optional)
        `ignoreAncestry` - if true then the ancestry of the two entries to be diffed is ignored, otherwise not
        `recursive` - if true and the diff scope is a directory, descends recursively, otherwise not
        `getContents` - if false contents (diff windows) will not be sent to the editor.
        `reporter` - a caller's reporter
        `editor` - a caller's editor
      Throws:
        `SVNException` - in the following cases:
        - `url` not found neither in the specified `revision` nor in the HEAD revision
        - a failure occured while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

                             throws SVNException

      Asks this repository access object to 'diff' a working copy against `targetRevision`.

      Note: this method cannot be used to diff a single file, only a directory. See the `update(SVNURL, long, String, SVNDepth, ISVNReporterBaton, ISVNEditor)` method for more details.

      The client initially provides an `editor`; this editor contains knowledge of where the common diff root is in the working copy (when `ISVNEditor.openRoot(long)` is called).

      In return, the client receives a `ISVNReporter` object in his `ISVNReporterBaton` implementation. The client then describes its working copy by making calls into the reporter object.

      When finished, the client calls `ISVNReporter.finishReport()`. This `SVNRepository` object then does a complete drive of `editor`, ending with `ISVNEditor.closeEdit()`, to transmit the diff.

      `target` is an optional single path component that will restrict the scope of things affected by the switch to an entry in the directory represented by the `location` of this object, or null if the entire directory is meant to be switched.

      The working copy will be diffed against `url` as it exists in revision `targeRevision`, or as it is in HEAD if `targetRevision` is invalid (`<0`).

      Use `ignoreAncestry` to control whether or not items being diffed will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is true, unrelated items will be diffed as if they were related.

      Diffs only as deeply as `depth` indicates.

      The caller may not perform any repository access operations using this `SVNRepository` object before finishing the report, and may not perform any repository access operations using this `SVNRepository` object from within the editing operations of `editor`.

      `getContents` instructs the driver of the `editor` to enable the generation of text deltas. If `getContents` is false the `editor`'s `ISVNDeltaConsumer.textDeltaChunk(String, SVNDiffWindow)` method will be called once with `SVNDiffWindow.EMPTY`.

      Note: the reporter provided by this function does NOT supply copy-from information to the diff editor callbacks.

      Note: in order to prevent pre-1.5 servers from doing more work than needed, and sending too much data back, a pre-1.5 'recurse' directive may be sent to the server, based on `depth`.
      Parameters:
        `url` - a repository location of the entry against which differences are calculated
        `targetRevision` - a revision number of the entry located at the specified `url`; defaults to the latest revision (HEAD) if this arg is invalid
        `revision` - a revision number of the repository location to which this driver object is set
        `target` - a target entry name (optional)
        `ignoreAncestry` - if true then the ancestry of the two entries to be diffed is ignored, otherwise not
        `depth` - tree depth to process
        `getContents` - if false contents (diff windows) will not be sent to the editor
        `reporter` - a caller's reporter
        `editor` - a caller's editor
      Throws:
        `SVNException` - in the following cases:
        - `url` not found neither in the specified `revision` nor in the HEAD revision
        - a failure occured while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

                               throws SVNException

      Gets status of a path to the particular `depth` as a scope. `status(long, String, boolean, ISVNReporterBaton, ISVNEditor)`
      Parameters:
        `revision` - a desired revision to get status against; defaults to the latest revision (HEAD)
        `target` - an entry name (optional)
        `depth` - defines the status scope
        `reporter` - a client's reporter-baton
        `editor` - a client's status editor
      Throws:

    - #### checkout

          public void checkout​(long revision,
                               java.lang.String target,

                        throws SVNException

      Checks out a directory from a repository.

      `target` is the name (one-level path component) of an entry that will restrict the scope of the checkout to this entry. In other words `target` is a child entry of the directory represented by the repository location to which this object is set. For example, if we have something like `"/dirA/dirB"` in a repository, then this object's repository location may be set to `"svn://host:port/path/to/repos/dirA"`, and `target` may be `"dirB"`.

      If `target` is null or empty (`""`) then the scope of the checkout operation is the repository location to which this object is set.

      The provided `editor` is used to carry out all the work on building a local tree of dirs and files being checked out.

      NOTE: you may not invoke methods of this SVNRepository object from within the provided `editor`.

      Parameters:
        `revision` - a desired revision of a dir to check out; defaults to the latest revision (HEAD)
        `target` - an entry name (optional)
        `recursive` - if true and the checkout scope is a directory, descends recursively, otherwise not
        `editor` - a caller's checkout editor
      Throws:
        `SVNException` - in the following cases:
        - the checkout scope is not a directory (only dirs can be checked out)
        - a failure occured while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

                        throws SVNException

      Checks out a directory from a repository to define `depth`.

      `target` is the name (one-level path component) of an entry that will restrict the scope of the checkout to this entry. In other words `target` is a child entry of the directory represented by the repository location to which this object is set. For example, if we have something like `"/dirA/dirB"` in a repository, then this object's repository location may be set to `"svn://host:port/path/to/repos/dirA"`, and `target` may be `"dirB"`.

      If `target` is null or empty (`""`) then the scope of the checkout operation is the repository location to which this object is set.

      The provided `editor` is used to carry out all the work on building a local tree of dirs and files being checked out.

      NOTE: you may not invoke methods of this SVNRepository object from within the provided `editor`.

      Parameters:
        `revision` - a desired revision of a dir to check out; defaults to the latest revision (HEAD)
        `target` - an entry name (optional)
        `depth` - the checkout operation scope
        `editor` - a caller's checkout editor
      Throws:
        `SVNException` - in the following cases:
        - the checkout scope is not a directory (only dirs can be checked out)
        - a failure occured while connecting to a repository

                                    java.lang.String[] paths,
                                    ISVNFileCheckoutTarget fileCheckoutHandler)
                             throws SVNException

      Recursively checks out only files from the repository at `revision` invoking `fileCheckoutHandler` on every file received.

      Instead of multiple calls to `getFileRevisions(String, long, long, boolean, ISVNFileRevisionHandler)` which lead to multiple requests to the repository server a user may use this method to get all interesting files.

      If `paths` is not null and not empty, checks out only those `paths`. It means if a path is from `paths` and is a file - checks out that file; if a directory - checks out every file under the directory and down the tree.

      Otherwise if `paths` is null or empty, checks out files from the entire tree under this object's `getLocation()`.

      `paths` does not have to be sorted; it will be sorted automatically.
      Parameters:
        `revision` - revision of files to checkout
        `paths` - paths to check out
        `fileCheckoutHandler` - caller's file data receiver
      Throws:
        `SVNException`

    - #### replay

          public abstract void replay​(long lowRevision,
                                      long revision,
                                      boolean sendDeltas,
                                      ISVNEditor editor)
                               throws SVNException

      Replays the changes from the specified revision through the given editor.

      Changes will be limited to those that occur under a session's URL, and the server will assume that the client has no knowledge of revisions prior to a `lowRevision`. These two limiting factors define the portion of the tree that the server will assume the client already has knowledge of, and thus any copies of data from outside that part of the tree will be sent in their entirety, not as simple copies or deltas against a previous version.

      If `sendDeltas` is true, the actual text and property changes in the revision will be sent, otherwise no text deltas and null property changes will be sent instead.

      If `lowRevision` is invalid, it defaults to 0.

      Parameters:
        `lowRevision` - a low revision point beyond which a client has no knowledge of paths history
        `revision` - a revision to replay
        `sendDeltas` - controls whether text and property changes are to be sent
        `editor` - a commit editor to receive changes
      Throws:
        `SVNException` - in case the repository could not be connected
        `SVNAuthenticationException` - in case of authentication problems
      Since:
        1.1, new in SVN 1.4

    - #### replayRange

          public void replayRange​(long startRevision,
                                  long endRevision,
                                  long lowRevision,
                                  boolean sendDeltas,
                                  ISVNReplayHandler handler)
                           throws SVNException

      Replays the changes from a range of revisions between `startRevision` and `endRevision`.

      When receiving information for one revision, `ISVNReplayHandler.handleStartRevision(long, SVNProperties)` is called; this method will provide an editor through which the revision will be replayed. When replaying the revision is finished, `ISVNReplayHandler.handleEndRevision(long, SVNProperties, ISVNEditor)` will be called so the editor can be closed.

      Changes will be limited to those that occur under this object's `getLocation()`, and the server will assume that the client has no knowledge of revisions prior to `lowRevision`. These two limiting factors define the portion of the tree that the server will assume the client already has knowledge of, and thus any copies of data from outside that part of the tree will be sent in their entirety, not as simple copies or deltas against a previous version.

      If `sendDeltas` is true, the actual text and property changes in the revision will be sent, otherwise dummy text deltas and null property changes will be sent instead.

      If the server does not support revision range replication, then invokes `replay(long, long, boolean, ISVNEditor)` on each revision between `startRevision` and `endRevision` inclusively.
      Parameters:
        `startRevision` - revision range start
        `endRevision` - revision range end
        `lowRevision` - low water mark revision
        `sendDeltas` - whether to ask the server send text and properties
        `handler` - caller's handler
      Throws:
        `SVNException` - in the following cases:
        exception with `SVNErrorCode.RA_NOT_IMPLEMENTED` error code - if the server does not support revision range replication

                                     throws SVNException

      Gets an editor for committing changes to a repository. Having got the editor traverse a local tree of dirs and/or files to be committed, handling them with corresponding methods of the editor.

      `mediator` is used for temporary delta data storage allocations.

      The root path of the commit is the current repository location to which this object is set.

      After the commit has succeeded `ISVNEditor.closeEdit()` returns an SVNCommitInfo object that contains a new revision number, the commit date, commit author.

      This method should be rather used with pre-1.2 repositories.

      NOTE: you may not invoke methods of this SVNRepository object from within the returned commit editor.

      Parameters:
        `logMessage` - a commit log message
        `mediator` - temp delta storage provider; used also to cache wcprops while committing
      Returns:
        an editor to commit a local tree of dirs and/or files
      Throws:
        `SVNException` - in the following cases:
        - the repository location this object is set to is not a directory
        - a failure occured while connecting to a repository

      Parameters:
        `path` - an item's path
        `revision` - a revision of the entry; defaults to the latest revision (HEAD)
      Returns:
        an SVNDirEntry containing information about the entry or null if there's no entry with at the specified `path` under the specified `revision`
      Throws:

                                              throws SVNException

      Gets an editor for committing changes to a repository. Having got the editor traverse a local tree of dirs and/or files to be committed, handling them with corresponding methods of the editor.

      `locks` is a map used to provide lock tokens on the locked paths. Keys are locked paths in a local tree, and each value for a key is a lock token. `locks` must live during the whole commit operation.

      If `keepLocks` is true, then the locked paths won't be unlocked after a successful commit. Otherwise, if false, locks will be automatically released.

      `mediator` is used for temporary delta data storage allocations.

      The root path of the commit is the current repository location to which this object is set.

      After the commit has succeeded `ISVNEditor.closeEdit()` returns an SVNCommitInfo object that contains a new revision number, the commit date, commit author.

      NOTE: you may not invoke methods of this SVNRepository object from within the returned commit editor.

      Parameters:
        `logMessage` - a commit log message
        `locks` - a map containing locked paths mapped to lock tokens
        `keepLocks` - true to keep existing locks; false to release locks after the commit
        `mediator` - temp delta storage provider; used also to cache wcprops while committing
      Returns:
        an editor to commit a local tree of dirs and/or files
      Throws:
        `SVNException` - in the following cases:
        - the repository location this object is set to is not a directory
        - a failure occured while connecting to a repository

                                     throws SVNException

      Returns an editor for committing changes to the repository ession, setting the revision properties from `revisionProperties` table. The revisions being committed against are passed to the editor methods, starting with the `revision` argument to `ISVNEditor.openRoot(long)`. The path root of the commit is this object's `location`.

      `revisionProperties` maps `String` property names to `SVNPropertyValue` property values. `revisionProperties` can not contain either of `SVNRevisionProperty.LOG`, `SVNRevisionProperty.DATE` or `SVNRevisionProperty.AUTHOR`.

      `locks`, if non-null, is a hash mapping `String` paths (relative to the `location` of this object) to `String` lock tokens. The server checks that the correct token is provided for each committed, locked path.

      If `keepLocks` is true, then does not release locks on committed objects. Else, automatically releasees such locks.

      The caller may not perform any repository access operations using this `SVNRepository` object before finishing the edit.
      Parameters:
        `logMessage` - commit log message
        `locks` - local locks on files
        `keepLocks` - whether to unlock locked files after the commit or not
        `revisionProperties` - custom revision properties
        `mediator` - temp delta storage provider; used also to cache wcprops while committing
      Returns:
        commit editor
      Throws:
        `SVNException` - in the following cases:
        exception with `SVNErrorCode.CLIENT_PROPERTY_NAME` error code - if `revisionProperties` contains any `svn:` namespace property

                             throws SVNException

      Locks path(s) at definite revision(s).

      Note that locking is never anonymous, so any server implementing this function will have to "pull" a username from the client, if it hasn't done so already.

      Each path to be locked is handled with the provided `handler`. If a path was successfully locked, the `handler`'s `handleLock()` is called that receives the path and either a lock object (representing the lock that was set on the path) or an error exception, if locking failed for that path.

      If any path is already locked by a different user and the `force` flag is false, then this call fails with throwing an SVNException. But if `force` is true, then the existing lock(s) will be "stolen" anyway, even if the user name does not match the current lock's owner.

      Paths can be both relative to the location of this driver and absolute to the repository root (starting with `"/"`).

      Parameters:
        `pathsToRevisions` - a map which keys are paths and values are revision numbers (as Longs); paths are strings and revision numbers are Long objects
        `comment` - a comment string for the lock (optional)
        `force` - true if the file is to be locked in any way (even if it's already locked by someone else)
        `handler` - if not null, the lock handler is invoked on each path to be locked
      Throws:
        `SVNException` - in the following cases:
        - `force` is false and a path is already locked by someone else
        - a revision of a path is less than its last changed revision
        - a path does not exist in the latest revision
        - a failure occured while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

    - #### unlock

          public abstract void unlock​(java.util.Map pathToTokens,
                                      boolean force,
                                      ISVNLockHandler handler)
                               throws SVNException

      Removes lock(s) from the file(s).

      Note that unlocking is never anonymous, so any server implementing this function will have to "pull" a username from the client, if it hasn't done so already.

      Each path to be unlocked is handled with the provided `handler`. If a path was successfully unlocked, the `handler`'s `handleUnlock()` is called that receives the path and either a lock object (representing the lock that was removed from the path) or an error exception, if unlocking failed for that path.

      If the username doesn't match the lock's owner and `force` is false, this method call fails with throwing an SVNException. But if the `force` flag is true, the lock will be "broken" by the current user.

      Also if the lock token is incorrect or null and `force` is false, the method fails with throwing a SVNException. However, if `force` is true the lock will be removed anyway.

      Paths can be both relative to the location of this driver and absolute to the repository root (starting with `"/"`).

      Parameters:
        `pathToTokens` - a map which keys are file paths and values are file lock tokens (both keys and values are strings)
        `force` - true to remove the lock in any case - i.e. to "break" the lock
        `handler` - if not null, the lock handler is invoked on each path to be unlocked
      Throws:
        `SVNException` - in the following cases:
        - `force` is false and the name of the user who tries to unlock a path does not match the lock owner
        - a lock token is incorrect for a path
        - a failure occurred while connecting to a repository
        - the user authentication failed (see `SVNAuthenticationException`)

    - #### closeSession

          public abstract void closeSession()

      Closes the current session closing a socket connection used by this object. If this driver object keeps a single connection for all the data i/o, this method helps to reset the connection.

    - #### hasCapability

          public abstract boolean hasCapability​(SVNCapability capability)
                                         throws SVNException

      Returns `true` if the repository has specified `capability`. This method may need to establish connection with the repository if information on capabilities has not been received yet from the repository.
      Parameters:
        `capability` - one of `SVNCapability`
      Returns:
        boolean if the repository has specified capability
      Throws:
        `SVNException` - in case the repository could not be connected
        `SVNAuthenticationException` - in case of authentication problems
      Since:

      See Also:
        `SVNCapability`

    - #### getOptions

          public ISVNSession getOptions()

      Returns the session options object this driver is using. If no options object was provided to create this driver then it uses a default one - `ISVNSession.DEFAULT`.
      Returns:
        a session options object

    - #### addConnectionListener

          public void addConnectionListener​(ISVNConnectionListener listener)

      Adds a connection listener to this object. There can be more than one connection listeners added to a single `SVNRepository` object.

      All the provided listeners will be notified each time by this object about a new connection which it's opening.

      Note: listeners are not notified in case of the `file:///` repository access protocol.
      Parameters:
        `listener` - caller's connection listener
      Since:
        1.2.0

    - #### removeConnectionListener

          public void removeConnectionListener​(ISVNConnectionListener listener)

      Removes the specified connection listener from the collection of connection listeners held by this object.
      Parameters:
        `listener` - connection listener to remove
      Since:
        1.2.0

                                  throws SVNException

      Returns the revision where the path was first deleted within the inclusive revision range defined by `pegRevision` and `endRevision`.

      If `path` does not exist at `pegRevision` or was not deleted within the specified range, then returns an invalid revision (`<0`).
      Parameters:
        `path` - relative or absolute repository path
        `pegRevision` - peg revision to start the search from
        `endRevision` - end revision to end the search at
      Returns:
        revision where `path` is first deleted
      Throws:
        `SVNException` - if `pegRevision` or `endRevision` are invalid or if `pegRevision` is greater than `endRevision`, then the exception is set `SVNErrorCode.CLIENT_BAD_REVISION` error code; if `path` is the repository root (`"/"`).
