Class ParanoidHashSet<T>

java.lang.Object

java.util.AbstractCollection<T>

java.util.AbstractSet<T>

java.util.HashSet<T>

java.util.LinkedHashSet<T>

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

All Implemented Interfaces:

Serializable, Cloneable, Iterable<T>, Collection<T>, SequencedCollection<T>, SequencedSet<T>, Set<T>

public class ParanoidHashSet<T>
extends LinkedHashSet<T>

a debugging aid. This implementation complains if you stick an object in here which appears to use System.identityHashCode(), or if it detects more than BAD_HC collisions in the Set (possibly indicated a bad hash function)
