AbstractKeyValueStore (xdi2-core 0.7.2 API)

java.lang.Object
- xdi2.core.impl.keyvalue.AbstractKeyValueStore

All Implemented Interfaces:

KeyValueStore

Direct Known Subclasses:

BDBKeyValueStore, MapKeyValueStore, PropertiesKeyValueStore
```
public abstract class AbstractKeyValueStore
extends Object
implements KeyValueStore
```
This abstract base class relieves subclasses from certain tasks by implementing them using other more basic methods. The basic methods that still have to be implemented are: - put(key, value) - getAll(key, value) - delete(key, value) Subclasses are still encouraged to overwrite as many methods as possible for better performance.
