org.alfresco.util.VmShutdownListener

public class VmShutdownListener
extends java.lang.Object

A class that keeps track of the VM shutdown status. It can be used by threads as a singleton to check if the VM shutdown status has been activated.

NOTE: In order to prevent a proliferation of shutdown hooks, it is advisable to use instances as singletons only.

This component should be used by long-running, but interruptable processes.
