java.lang.Object
  java.util.logging.LogManager
      org.apache.juli.ClassLoaderLogManager

public class ClassLoaderLogManager
extends java.util.logging.LogManager

Per classloader LogManager implementation.

classLoaderLoggers

protected final java.util.Map<java.lang.ClassLoader,ClassLoaderLogManager.ClassLoaderLogInfo> classLoaderLoggers

Map containing the classloader information, keyed per classloader. A weak hashmap is used to ensure no classloader reference is leaked from application redeployment.

prefix

protected java.lang.ThreadLocal<java.lang.String> prefix

This prefix is used to allow using prefixes for the properties names of handlers and their subcomponents.

useShutdownHook

protected volatile boolean useShutdownHook

Determines if the shutdown hook is used to perform any necessary clean-up such as flushing buffered handlers on JVM shutdown. Defaults to true but may be set to false if another component ensures that shutdown() is called.

addLogger

public boolean addLogger(java.util.logging.Logger logger)
