Class StringMatchFilter

      extended by org.apache.log4j.varia.StringMatchFilter
All Implemented Interfaces:
OptionHandler

public class StringMatchFilter
extends Filter

This is a very simple filter based on string matching.

The filter admits two options StringToMatch and AcceptOnMatch. If there is a match between the value of the StringToMatch option and the message of the LoggingEvent, then the decide(LoggingEvent) method returns Filter.ACCEPT if the AcceptOnMatch option value is true, if it is false then Filter.DENY is returned. If there is no match, Filter.NEUTRAL is returned.
