public class ObjectReferenceSet<T>
extends java.util.AbstractSet<T>
implements java.util.Set<T>

A set that stores objects by reference rather than hash. Equality is true only if references are equal, ie obj1 == obj2. Note that this is O(n), o(1). Internally, the objects are stored by class. Immutable types (known ones) are stored by hash, whereas others are stored in a list. Author: Mike Date: 1/6/12 Time: 6:29 PM
