Class ContextClassLoaderRepositorySelector

java.lang.Object

com.revolsys.logging.log4j.ContextClassLoaderRepositorySelector

All Implemented Interfaces:

org.apache.log4j.spi.RepositorySelector

public class ContextClassLoaderRepositorySelector
extends Object
implements org.apache.log4j.spi.RepositorySelector

The ContextClassLoaderRepositorySelector class is used to manage different LoggerRepository heirarchies for different context class loaders. The add() method can be used to create a seperate logger repository for the current thread context class loader. When the class loader is about to be destroyed use the remove() method to clean up the logger repository for the class loader. See the Log4jServletContextListener for use in web applications.
