Set facility name.

### Get_Name

Write message with specified log level. This procedure must be implemented by all facilities.

### Toggle_Write_Timestamp

- Goto spec in source

    procedure Toggle_Write_Timestamp (Facility: in out Class;State:        Boolean);

Enable/disable whether a timestamp is written for log messages.

### Toggle_UTC_Timestamp

- Goto spec in source

    procedure Toggle_UTC_Timestamp (Facility: in out Class;State:        Boolean);

Enable/disable UTC timestamps for log messages.

### Is_Write_Timestamp

- Goto spec in source

    function Is_Write_Timestamp (Facility: Class) return Boolean;

Returns the current value of Write_Timestamp.

### Is_UTC_Timestamp

- Goto spec in source

    function Is_UTC_Timestamp (Facility: Class) return Boolean;

Returns True if the timestamp of the facility is written in UTC time.

### Toggle_Write_Loglevel

- Goto spec in source

    procedure Toggle_Write_Loglevel (Facility: in out Class;State:        Boolean);

Enable/disable whether the loglevel is written for log messages.

### Is_Write_Loglevel

Returns True if writing of log message sources is enabled.

### Setup

- Goto spec in source

    procedure Setup (Facility: in out Instance) is null;

Each facility must provide a Setup-procedure. These procedures are called by Logger instances when attaching Facilities. All needed operations prior to writing log messages should be done here.

### Teardown

- Goto spec in source

    procedure Teardown (Facility: in out Instance) is null;

Each facility must provide a Teardown-procedure. These procedures are called by Logger instances when detaching Facilities or when the logger object gets out of scope.
