Method Detail

Overrides:

append

public void append(LoggingEvent event)

This method is called by the AppenderSkeleton.doAppend(org.apache.log4j.spi.LoggingEvent) method.

Specified by:

append in class AppenderSkeleton

close

public void close()

Description copied from interface: Appender

Release any resources allocated within the appender such as file handles, network connections, etc.

It is a programming error to append to a closed appender.

getVector

public Vector getVector()

isClosed

public boolean isClosed()

requiresLayout

public boolean requiresLayout()

Description copied from interface: Appender

Configurators call this method to determine if the appender requires a layout. If this method returns true, meaning that layout is required, then the configurator will configure an layout using the configuration information at its disposal. If this method returns false, meaning that a layout is not required, then layout configuration will be skipped even if there is available layout configuration information at the disposal of the configurator..

In the rather exceptional case, where the appender implementation admits a layout but can also work without it, then the appender should return true.

Returns:

true if a Layout is required.
