Class GenericHandler

java.lang.Object
  org.objectweb.util.monolog.wrapper.log4j.GenericHandler

All Implemented Interfaces:

org.apache.log4j.Appender, Handler

public class GenericHandler
extends Object
implements org.apache.log4j.Appender, Handler

This class is a generic implementation of the Handler interface. This class delegates all calls on a log4j Appender. It is also an Appender interceptor. This class can therefore be referenced into the log4j struture as an Appender. There are three ways to specify the inner Appender:

• by the construstor with the appender instance
• by the setAppender method with the appender instance
• by the setAttribute method with the appender class name. This method tries to instanciate the class, and initializes the new Appender with all attribute which has been specified before. Even the filters and the layout are memorized.
