ExtObjectServer SourceCode GPL - https://github.com/iboxdb/db4o-gpl

All Superinterfaces:

ObjectServer

All Known Implementing Classes:

ObjectServerImpl
```
public interface ExtObjectServer
extends ObjectServer
```
extended functionality for the ObjectServer interface.

Every ObjectServer also always is an ExtObjectServer so a cast is possible.

ObjectServer.ext() is a convenient method to perform the cast.

The functionality is split to two interfaces to allow newcomers to focus on the essential methods.
