Class WorkSet<E>

java.lang.Object
java.util.AbstractCollection<E>
java.util.AbstractSet<E>
net.cscott.jutil.WorkSet<E>
All Implemented Interfaces:
Serializable, Iterable<E>, Collection<E>, Set<E>
@Deprecated(since="1.3") public class WorkSet<E> extends AbstractSet<E> implements Serializable
Deprecated.
Use LinkedHashSet instead.
A WorkSet is a Set offering constant-time access to the first/last element inserted, and an iterator whose speed is not dependent on the total capacity of the underlying hashtable.

Conforms to the JDK 1.2 Collections API.
