com.ibm.wala.util.collections.ObjectArrayMapping<T>

All Implemented Interfaces:

OrdinalSetMapping<T>, Iterable<T>

public class ObjectArrayMapping<T>
extends Object
implements OrdinalSetMapping<T>

A bit set mapping based on an immutable object array. This is not terribly efficient, but is useful for prototyping.
