@Deprecated
public class RWLockManager<OBJECT,CONTEXT>
  
extends Lifecycle
  
implements IRWLockManager<OBJECT,CONTEXT>

Support Multiple reads/no write and upgrade lock from read to write. Many context could request write lock at the same time. It will privileges first context that has already a read lock. If no one has any read lock, it's "first come first serve".

2.0
