Examples of ListAppender

ch.qos.logback.core.read.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
org.apache.logging.log4j.test.appender.ListAppender
This appender is primarily used for testing. Use in a real environment is discouraged as the List could eventually grow to cause an OutOfMemoryError. @see org.apache.logging.log4j.junit.InitialLoggerContext#getListAppender(String) ILC.getListAppender
org.slf4j.dummyExt.ListAppender
