Detailed Description

FilterBasedTriggeringPolicy determines if rolling should be triggered by evaluating the current message against a set of filters.

Unless a filter rejects a message, a rolling event will be triggered.

Member Function Documentation

addFilter()

void log4cxx::rolling::FilterBasedTriggeringPolicy::addFilter

(

const log4cxx::spi::FilterPtr &

newFilter

)

Add a filter to end of the filter list.

Parameters

newFilter

filter to add to end of list.

isTriggeringEvent()

virtual bool log4cxx::rolling::FilterBasedTriggeringPolicy::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

appender	A reference to the appender.
event	A reference to the currently event.
filename	The filename for the currently active log file.
fileLength	Length of the file in bytes.

Returns

true if a rollover should occur.

Implements log4cxx::rolling::TriggeringPolicy.

setOption()

void log4cxx::rolling::FilterBasedTriggeringPolicy::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 log4cxx::spi::OptionHandler.
