All Implemented Interfaces:

IRWLockManager<OBJECT,CONTEXT>, INotifier, INotifier.INotifier2, IDeactivateable, ILifecycle, ILifecycle.DeferrableActivation
```
@Deprecated
public class RWLockManager<OBJECT,CONTEXT>
extends Lifecycle
implements IRWLockManager<OBJECT,CONTEXT>
```
Deprecated.
As of 3.2 use RWOLockManager.

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".

Since:

2.0
