All Implemented Interfaces:

ILockableWorldView, IWorldChangeEventInput, IWorldView, IComponent

public class LockableWorldView
extends EventDrivenWorldView
implements ILockableWorldView

WorldView that can be locked. If the world is locked all chages on objects are postponed and issued when the world is unlocked. The events aren't locked by default, but there is a switch that enables locking of events.

Field Summary

protected java.util.List<IWorldChangeEvent>	eventsToProcess List of events received when the worldview was locked.
protected boolean	lockEvents Lock non object update events?
