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 LevelMin
w 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.
log4cxx::filter::LevelRangeFilter::LevelRangeFilter | ( | ) |
|
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.
