Method Summary

protected abstract boolean	isBatchBeginEvent(IWorldChangeEvent evt) Is this event a batch begin event? It is needed for the locking to be working correctly.
boolean	isLocked() Whether the worldview is locked.
void	lock() When the world view is locked - no batches are processes until unlocked.
void	notify(IWorldChangeEvent event) Implements locking logic.
void	unlock() Unlocks the world view - triggers processing of all events till the last EndMessage that came between lock() / unlock() calls.
