Class DestroyHandlingStateOp

java.lang.Object

org.oddjob.state.DestroyHandlingStateOp

All Implemented Interfaces:

StateOperator

public class DestroyHandlingStateOp
extends Object
implements StateOperator

Handle a destroyed state. Most StateOperators don't need to handle the destroyed state because the Arooa Framework ensures that a child is removed from a parent before it is destroyed. There are however situations where a job adds it's own children and must cope with them being destroyed. RunJob is one such example.
