WriteBack (server 0.4.5-SNAPSHOT API)

java.lang.Object
- org.vrspace.server.core.WriteBack

```
@Component
public class WriteBack
extends Object
```
Experimental thread-safe write-back component. Clients may send more events than can be stored into the database. Typically, the most frequent events originate from client movement. While movement events need to be propagated, they doesn't need to be persisted each and every time, as long as client coordinates are consistent overall. This component collects all changed objects, and saves them after configurable delay, all in one one batch. Used by WorldManager.
