Class WeakReferenceSet<E>

java.lang.Object

com.qualcomm.robotcore.util.WeakReferenceSet<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>

public class WeakReferenceSet<E>
extends java.lang.Object
implements java.util.Set<E>

WeakReferenceSet has set behaviour but contains weak references, not strong ones. WeakReferenceSet is thread-safe. It's designed primarily for relatively small sets, as the implementation employed is inefficient on large sets.
