RWLockManager (Net4j Utilities Documentation)

java.lang.Object
- org.eclipse.net4j.util.event.Notifier
- - org.eclipse.net4j.util.lifecycle.Lifecycle
  - - org.eclipse.net4j.util.concurrent.RWLockManager<OBJECT,CONTEXT>

All Implemented Interfaces:

IRWLockManager<OBJECT,CONTEXT>, INotifier, ILifecycle, ILifecycle.DeferrableActivation

Deprecated.
Use RWOLockManager
```
@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".

Since:

2.0
