LevelRangeFilter (Log4j Version 1.2.14)

Class LevelRangeFilter

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 {@link LoggingEvent} is not between Min and Max (inclusive), then {@link Filter#DENY} is returned.

If the Logging event level is within the specified range, then if AcceptOnMatch is true, {@link Filter#ACCEPT} is returned, and if AcceptOnMatch is false, {@link 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 {@link org.apache.log4j.AppenderSkeleton#setThreshold setThreshold} method available to all appenders extending {@link org.apache.log4j.AppenderSkeleton} for a more convenient way to filter out events by level.
