## Class IdentityScope

- java.lang.Object
- - java.security.Identity
  - - java.security.IdentityScope

All Implemented Interfaces:
  Serializable, Principal

Deprecated.
This class is no longer used. Its functionality has been replaced by `java.security.KeyStore`, the `java.security.cert` package, and `java.security.Principal`.

    @Deprecated
    public abstract class IdentityScope
    extends Identity

This class represents a scope for identities. It is an Identity itself, and therefore has a name and can have a scope. It can also optionally have a public key and associated certificates.

An IdentityScope can contain Identity objects of all kinds, including Signers. All types of Identity objects can be retrieved, added, and removed using the same methods. Note that it is possible, and in fact expected, that different types of identity scopes will apply different policies for their various operations on the various types of Identities.

There is a one-to-one mapping between keys and identities, and there can only be one copy of one key per scope. For example, suppose Acme Software, Inc is a software publisher known to a user. Suppose it is an Identity, that is, it has a public key, and a set of associated certificates. It is named in the scope using the name "Acme Software". No other named Identity in the scope has the same public key. Of course, none has the same name as well.

### Constructor Detail

#### IdentityScope

    protected IdentityScope()

Deprecated.
This constructor is used for serialization only and should not be used by subclasses.

#### IdentityScope

    public IdentityScope(String name)

Deprecated.
Constructs a new identity scope with the specified name.

Parameters:
  `name` - the scope name.

#### IdentityScope

    public IdentityScope(String name,
                         IdentityScope scope)
                  throws KeyManagementException

Deprecated.
Constructs a new identity scope with the specified name and scope.

Parameters:
  `name` - the scope name.
  `scope` - the scope for the new identity scope.
Throws:
  `KeyManagementException` - if there is already an identity with the same name in the scope.

### Method Detail

#### getSystemScope

    public static IdentityScope getSystemScope()

Deprecated.
Returns the system's identity scope.

Returns:
  the system's identity scope, or `null` if none has been set.
See Also:
  `setSystemScope(java.security.IdentityScope)`

#### setSystemScope

    protected static void setSystemScope(IdentityScope scope)

Deprecated.
Sets the system's identity scope.

First, if there is a security manager, its `checkSecurityAccess` method is called with `"setSystemScope"` as its argument to see if it's ok to set the identity scope.

Parameters:
  `scope` - the scope to set.
Throws:
  `SecurityException` - if a security manager exists and its `checkSecurityAccess` method doesn't allow setting the identity scope.
See Also:
  `getSystemScope()`, `SecurityManager.checkSecurityAccess(java.lang.String)`

#### size

    public abstract int size()

Deprecated.
Returns the number of identities within this identity scope.

Returns:
  the number of identities within this identity scope.

#### getIdentity

    public abstract Identity getIdentity(String name)

Deprecated.
Returns the identity in this scope with the specified name (if any).

Parameters:
  `name` - the name of the identity to be retrieved.
Returns:
  the identity named `name`, or null if there are no identities named `name` in this scope.

#### getIdentity

    public Identity getIdentity(Principal principal)

Deprecated.
Retrieves the identity whose name is the same as that of the specified principal. (Note: Identity implements Principal.)

Parameters:
  `principal` - the principal corresponding to the identity to be retrieved.
Returns:
  the identity whose name is the same as that of the principal, or null if there are no identities of the same name in this scope.

#### getIdentity

    public abstract Identity getIdentity(PublicKey key)

Deprecated.
Retrieves the identity with the specified public key.

Parameters:
  `key` - the public key for the identity to be returned.
Returns:
  the identity with the given key, or null if there are no identities in this scope with that key.

#### addIdentity

    public abstract void addIdentity(Identity identity)
                              throws KeyManagementException

Deprecated.
Adds an identity to this identity scope.

Parameters:
  `identity` - the identity to be added.
Throws:
  `KeyManagementException` - if the identity is not valid, a name conflict occurs, another identity has the same public key as the identity being added, or another exception occurs.

#### removeIdentity

    public abstract void removeIdentity(Identity identity)
                                 throws KeyManagementException

Deprecated.
Removes an identity from this identity scope.

Parameters:
  `identity` - the identity to be removed.
Throws:
  `KeyManagementException` - if the identity is missing, or another exception occurs.

#### identities

    public abstract Enumeration<Identity> identities()

Deprecated.
Returns an enumeration of all identities in this identity scope.

Returns:
  an enumeration of all identities in this identity scope.

#### toString

    public String toString()

Deprecated.
Returns a string representation of this identity scope, including its name, its scope name, and the number of identities in this identity scope.

Specified by:
  `toString` in interface `Principal`
Overrides:
  `toString` in class `Identity`
Returns:
  a string representation of this identity scope.
