  • Field Details

    • DEBUG_PROPERTY

      public static final String DEBUG_PROPERTY

    • classLoaderLoggers

      protected final Map<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 final ThreadLocal<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.
