Member Function Documentation

_append()

void log4cpp::OstreamAppender::_append ( const LoggingEvent &  event )

protectedvirtual

Log in Appender specific way.

Subclasses of Appender should implement this method to perform actual logging.

Parameters

event

The LoggingEvent to log.

Implements log4cpp::AppenderSkeleton.

close()

void log4cpp::OstreamAppender::close ( )

virtual

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

Implements log4cpp::AppenderSkeleton.

reopen()

bool log4cpp::OstreamAppender::reopen ( )

virtual

Reopens the output destination of this Appender, e.g.

the logfile or TCP socket.

Returns

false if an error occured during reopening, true otherwise.

Reimplemented from log4cpp::AppenderSkeleton.
