Class UnmodifiableMergingMapView<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.eclipse.xtext.xbase.lib.internal.UnmodifiableMergingMapView<K,V>

Type Parameters:

K - the type of the keys.

V - the type of the values in the maps.

All Implemented Interfaces:

Map<K,V>

@GwtCompatible
public class UnmodifiableMergingMapView<K,V>
extends AbstractMap<K,V>

Map implementation that is merging two maps.

If a key exists within the two merged maps, then the retained value is the one of the right map.

Since:

2.15
