public class USAR2004SyncLockableWorldView
extends USAR2004WorldView
implements cz.cuni.amis.pogamut.base3d.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().

lock() method here blocks until the END message of the batch is hit, then the world view is considered to be fully locked and let the lock() continue. You may use it to create correct sync bot. (just lock() the world view before your logic and unlock() the world view after the logic finishes)

The world view is unlocked from the beginning.

The locking mechanism starts to work with the first BeginMessage. (To let all other events to be processed automatically during the handshake.)
