Class MCRShutdownHandler

java.lang.Object
  org.mycore.common.events.MCRShutdownHandler

public class MCRShutdownHandler
extends Object

is a wrapper for shutdown hooks. When used inside a web application this shutdown hook is bound to the ServletContext. If not this hook is bound to the Java Runtime. Every Closeable that is added via addCloseable() will be closed at shutdown time. Do not forget to remove any closeable via removeCloseable() to remove any instances. For registering this hook for a web application see MCRServletContextListener
