All Implemented Interfaces:

Map<T,Integer>

public class MemoryViewBackedMapView<T>
extends Object
implements Map<T,Integer>

A partial and read-only Map implementation, mapping elements to multiplicities backed by an IMemoryView.

Not implemented: write methods.

Inefficiently implemented: containsValue(Object), values(), entrySet().
