- org.eclipse.core.databinding.observable.AbstractObservable
- - org.eclipse.core.databinding.observable.map.ObservableMap<K,V>

Type Parameters:

K - the type of the keys in this map

V - the type of the values in this map

All Implemented Interfaces:

Map<K,V>, IObservable, IObservableMap<K,V>

Direct Known Subclasses:

BidirectionalMap, CompositeMap, WritableMap
```
public class ObservableMap<K,V>
extends AbstractObservable
implements IObservableMap<K,V>
```
This class is thread safe. All state accessing methods must be invoked from the current realm. Methods for adding and removing listeners may be invoked from any thread.
