Class HashtableLite

java.lang.Object
  |
  +--calypso.util.HashtableLite
public class HashtableLite
extends java.lang.Object
implements java.lang.Cloneable

A utility class to avoid the pain (and memory bloat) of making lots of small hashtables. A real HashTable isn't created until the number of elements grows past a certain number (defined internally to HashtableLite). It sure would have been nice if Hashtables were an interface.
