Class ConsistentSet<E>

java.lang.Object
  java.util.AbstractCollection<E>
      java.util.AbstractSet<E>
          org.intermine.util.ConsistentSet<E>

Type Parameters:

E - The element type

All Implemented Interfaces:

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

public class ConsistentSet<E>
extends java.util.AbstractSet<E>

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.

Constructor Summary

ConsistentSet()
Constructor.

Method Summary

boolean	add(E obj) Add an object to the set.
boolean	addAll(java.util.Collection<? extends E> col) Add a whole Collection of objects to the set.
java.util.Iterator<E>	iterator() Return an iterator for the elements in the Set.
int	size() Return the number of elements in this Set.
