public class UT2004LockableWorldView
extends UT2004WorldView
implements ILockableVisionWorldView

Lockable word view.

Contains GameBots2004 correct locking of the worldview.

All messages are processed always in batches (all messages between EndMessages are one batch) meaning that the world view is always correct!

When worldview is lock()ed it postpones the events until unlock()ed, which is triggering raising all events that came from the lock().

The world view is unlocked from the beginning.

All those locking mechanisms start working when the first BEGIN message comes.
