class
LockableHashtable
extends Hashtable
This subclass of the java Hashtable allows individual
entries to be "locked" so that their values cannot be
overwritten or removed.
Note, only the put() and remove() methods have been
overridden. The clear() method still removes all
entries whether they've been locked or not.
