Examples of org.apache.log4j.varia.ListAppender

org.apache.log4j.varia.ListAppender
A very basic appender that takes the events and stores them in to a java.util.List for late retrieval. Note: This implemenation intentionally does not allow direct modification of the internal List model to reduce the synchronization complexity that this would require. @see org.apache.log4j.varia.ListModelAppender @author Paul Smith
