Member Function Documentation

bool send

(

const string &

message

)

[private, virtual]

Sends a raw string message to the Logger's underlying device.

Parameters:

message

: Message to be sent.

Returns:

This method returns false if it fails. Otherwise, it returns true.

Implements LoggerImpl< AddPrefix, XtermColour >.

virtual unsigned int getLevel

(

)

const [pure virtual, inherited]

Gets Logger's current level.

Returns:

The level.

Implemented in LoggerImpl< PrefixPolicy, ColourPolicy, SafetyPolicy >.

virtual void setLevel

(

unsigned int

level

)

[pure virtual, inherited]

Sets Logger's current level.

Parameters:

level

: New level.

Implemented in LoggerImpl< PrefixPolicy, ColourPolicy, SafetyPolicy >.

virtual bool log

(

const Message &

message

)

[pure virtual, inherited]

Logs a Message.

This method may fail if the implemented Logger cannot process the message (e.g. a console Logger that has no longer a console window).

Parameters:

message

: Message to be logged.

Returns:

This method returns true if it is successful.

Implemented in LoggerImpl< PrefixPolicy, ColourPolicy, SafetyPolicy >.

bool sendHeader

(

)

[protected, inherited]

Sends the header message.

This method sends (throw send()) an opening header message to the underlying device of the Logger.

Returns:

This method returns what print() does.
