Constructor & Destructor Documentation

Member Function Documentation

void activateOptions ( log4cxx::helpers::Pool p)
virtual

Activate the options that were previously set with calls to option setters.

This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.

For example, the FileAppender has the File and Append options both of which are ambigous until the other is also set.

Implements OptionHandler.

size_t getMaxFileSize ( )
virtual bool isTriggeringEvent ( Appender appender,
const log4cxx::spi::LoggingEventPtr event,
const LogString filename,
size_t  fileLength 
)
virtual

Determines if a rollover may be appropriate at this time.

If true is returned, RolloverPolicy.rollover will be called but it can determine that a rollover is not warranted.

Parameters
appenderA reference to the appender.
eventA reference to the currently event.
filenameThe filename for the currently active log file.
fileLengthLength of the file in bytes.
Returns
true if a rollover should occur.

Implements TriggeringPolicy.

void setMaxFileSize ( size_t  l)
void setOption ( const LogString option,
const LogString value 
)
virtual

Set option to value.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Implements OptionHandler.
