Detailed Description

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 method returns ACCEPT if the AcceptOnMatch option value is true, if it is false then DENY is returned. If there is no match, NEUTRAL is returned.

See configuration files test6.xml, test7.xml, test8.xml, test9.xml, and test10.xml for examples of seeting up a StringMatchFilter.
