Hashtable
org.apache.axis.utils.LockableHashtable
public 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.

Object | get(Object key) - Get an entry from this hashtable, and if we don't find anything,
defer to our parent, if any.
|
Set | getAllKeys() - Returns the keys in this hashtable, and its parent chain
|
Hashtable | getParent() - Gets the parent Hashtable for this object (if any)
|
boolean | isKeyLocked(Object key) - Returns true if a given key is in our locked list
|
Object | put(Object p1, Object p2) - Overrides the Hashtable.put() method to mark items as not being locked.
|
Object | put(Object p1, Object p2, boolean locked) - New version of the put() method that allows for explicitly marking
items added to the hashtable as locked.
|
Object | remove(Object p1) - Checks to see if an item is locked before it is removed.
|
void | setParent(Hashtable parent) - Set the parent Hashtable for this object
