Package: Policy_DB

- Goto spec source

# Description

    package Alog.Policy_DB is

Logging policy database package. This DB stores logging policies. Policies in the database are used inside the framework for logging decisions.

# Constants & Global variables

### Alog_Default_Level

- Goto declaration in source

(Alog.Log_Level)

    Alog_Default_Level : constant Log_Level := Info;

Framework default loglevel.

### No_Ident_Loglevel

- Goto declaration in source

    No_Ident_Loglevel : exception;

Will be raised if loglevel is not found for a requested identifier.

# Subprograms & Entries

### Set_Default_Loglevel

- Goto spec in source

    procedure Set_Default_Loglevel (Level: Log_Level);

Set given loglevel as default loglevel.

### Get_Default_Loglevel

- Goto spec in source

    function Get_Default_Loglevel return Log_Level;

Return current default loglevel.

### Set_Loglevel

- Goto spec in source

    procedure Set_Loglevel (Identifier: String;Level: Log_Level);

Set given loglevel for specified identifier string. If the identifier is already present the loglevel is updated. Identifier strings are case-sensitive. Use wildcards to specify a loglevel for a range of identifiers. Identifier hierarchies are separated by dots, the wildcard is '*'. The following example sets a Debug loglevel for all log-identifiers in Foo.Bar (including Foo.Bar). Example: Foo.Bar.* = Debug Direct matches take precedence over wildcard matches. In the following example the loglevel for identifier 'Foo.Bar' is explicitly set to Info. Example: Foo.Bar = Info Foo.Bar.* = Debug

### Set_Loglevel

- Goto spec in source

    procedure Set_Loglevel (Identifiers: Maps.Wildcard_Level_Map);

Apply loglevels for identifiers stored in map.

### Get_Loglevel

- Goto spec in source

    function Get_Loglevel (Identifier: String) return Log_Level;

Return loglevel for given identifier string. Raises No_Ident_Loglevel exception if no entry for given identifier is found (exact match only, no wildcard lookup).

### Lookup

- Goto spec in source

    function Lookup (Identifier: String) return Log_Level;

Return loglevel for given identifier string. Returns the closest match, if no associated loglevel is found the default loglevel is returned.

### Reset

- Goto spec in source

    procedure Reset;

Reset the logging policy database to the initial state.

### Accept_Src

- Goto spec in source

    function Accept_Src (Identifier: String := "";Level: Log_Level) return Boolean;

Returns True if the given loglevel is accepted for a source identifier. If no identifier is given, the loglevel is verified against the default loglevel.

### Accept_Dst

- Goto spec in source

    function Accept_Dst (Identifier: String;Level: Log_Level) return Boolean;

Returns True if the given loglevel is accepted for a destination identifier. If no match for the given identifier is found True is returned.
