Detailed Description

This is a very simple filter based on level matching, which can be used to reject messages with priorities outside a certain range.

The filter admits three options LevelMin, LevelMax and AcceptOnMatch.

If the level of the LoggingEvent is not between Min and Max (inclusive), then DENY is returned.

If the Logging event level is within the specified range, then if AcceptOnMatch is true, ACCEPT is returned, and if AcceptOnMatch is false, NEUTRAL is returned.

If LevelMinw is not defined, then there is no minimum acceptable level (ie a level is never rejected for being too "low"/unimportant). If LevelMax is not defined, then there is no maximum acceptable level (ie a level is never rejected for beeing too "high"/important).

Refer to the setThreshold method available to all appenders extending AppenderSkeleton for a more convenient way to filter out events by level.

◆ decide()

FilterDecision log4cxx::filter::LevelRangeFilter::decide ( const spi::LoggingEventPtr event) const
virtual

Return the decision of this filter.

Returns NEUTRAL if the LevelToMatch option is not set or if there is not match. Otherwise, if there is a match, then the returned decision is ACCEPT if the AcceptOnMatch property is set to true. The returned decision is DENY if the AcceptOnMatch property is set to false.

Implements log4cxx::spi::Filter.

◆ getAcceptOnMatch()

bool log4cxx::filter::LevelRangeFilter::getAcceptOnMatch ( ) const
inline

Get the value of the AcceptOnMatch option.

◆ getLevelMax()

const LevelPtr& log4cxx::filter::LevelRangeFilter::getLevelMax ( ) const
inline

Get the value of the LevelMax option.

◆ getLevelMin()

const LevelPtr& log4cxx::filter::LevelRangeFilter::getLevelMin ( ) const
inline

Get the value of the LevelMin option.

◆ setAcceptOnMatch()

void log4cxx::filter::LevelRangeFilter::setAcceptOnMatch ( bool  acceptOnMatch1)
inline

Set the AcceptOnMatch option.

◆ setLevelMax()

void log4cxx::filter::LevelRangeFilter::setLevelMax ( const LevelPtr levelMax1)
inline

Set the LevelMax option.

◆ setLevelMin()

void log4cxx::filter::LevelRangeFilter::setLevelMin ( const LevelPtr levelMin1)
inline

Set the LevelMin option.

◆ setOption()

virtual void log4cxx::filter::LevelRangeFilter::setOption ( const LogString option,
const LogString value 
)
virtual

Set options.

Implements log4cxx::spi::OptionHandler.
