Handler, HandlerContainer, Destroyable, Dumpable, LifeCycle

Direct Known Subclasses:

ConnectHandler, DebugHandler, GzipHandler, IPAccessHandler, RequestLogHandler, ResourceHandler, ScopedHandler, Server, StatisticsHandler

public class HandlerWrapper
extends AbstractHandlerContainer

A HandlerWrapper acts as a Handler but delegates the handle method and life cycle events to a delegate. This is primarily used to implement the Decorator pattern.
