public class ConsistentSet
extends java.util.AbstractSet

A Set that allows for its member objects to be changed whilst still belonging to the set. Normally, this would result in unspecified behavior, as the hashCode() for the objects may change once added. If elements are changed so that two elements are made equal, behaviour is unspecified.
