Class WeakHashLongMap<T>

java.lang.Object
  av.util.WeakHashLongMap<T>

All Implemented Interfaces:

LongMap<T>, Iterable<T>

public class WeakHashLongMap<T>
extends Object
implements LongMap<T>, Iterable<T>

A simple hash implementation of the LongMap interface.

This map stores values via WeakReference, so won't prevent the objects inside from being garbage collected.
