Package org.eclipse.core.databinding.observable.map

Interface IObservableMap<K,V>

Type Parameters:

K - type of the keys in the map

V - type of the values in the map

All Superinterfaces:

IObservable, Map<K,V>

All Known Implementing Classes:

AbstractObservableMap, BidiObservableMap, BidirectionalMap, CompositeMap, ComputedObservableMap, DecoratingObservableMap, ObservableMap, WritableMap

public interface IObservableMap<K,V>
extends Map<K,V>, IObservable

Observable Map.

Since:

1.1

Restriction:

This interface is not intended to be implemented by clients. Clients should instead subclass one of the classes that implement this interface.

Authors of extensions to the databinding framework may extend this interface and indirectly implement it, but if doing so must also extend one of the framework classes. (Use an API problem filter to suppress the resulting warning.)

Direct implementers of this interface outside of the framework will be broken in future releases when methods are added to this interface.
