Class UnmodifiableMergingMapView<K,​V>

  • Type Parameters:
    K - the type of the keys.
    V - the type of the values in the maps.
    All Implemented Interfaces:
    java.util.Map<K,​V>

    @GwtCompatible
    public class UnmodifiableMergingMapView<K,​V>
    extends java.util.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.
