All Implemented Interfaces:

public class LevelRangeFilter extends Filter
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 Filter.DENY is returned.

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