Class IfsShutdownHook

java.lang.Object

ifs.fnd.service.IfsShutdownHook

public abstract class IfsShutdownHook
extends java.lang.Object

IFS specific replacement for functionality offered by java.lang.Runtime.addShutdownHook(). Create your hook classes by extending this class instead of java.lang.Thread and implementing the run() method. Use the static method addShutdownHook() from this class to register your hook.

The managed shutdown procedure can be started by the Java VM in a shutdown hook operation, but also from other hooks that shouldn't be started before this hook is done, i.e. loggers.
