public DowngradeActionMap() 
{
    actionMap = new HashMap();
    actionList = new ArrayList();
}

Default Constructor. Creates a new empty map.

 public Object[] allKeys() 
{
    if (parent == null)
    {
      return keys();
    }
    final Object[] parentKeys = parent.allKeys();
    final Object[] key = keys();
    final Object[] retval = new Object[parentKeys.length + key.length];
    System.arraycopy(key, 0, retval, 0, key.length);
    System.arraycopy(retval, 0, retval, key.length, retval.length);
    return retval;
}

Returns an array of the keys defined in this ActionMap and its parent. This method differs from keys() in that this method includes the keys defined in the parent.

 public  void clear() 
{
    actionMap.clear();
    actionList.clear();
}

Removes all the mappings from this ActionMap.

 public Action get(Object key) 
{
    final Action retval = (Action) actionMap.get(key);
    if (retval != null)
    {
      return retval;
    }
    if (parent != null)
    {
      return parent.get(key);
    }
    return null;
}

Returns the binding for key, messaging the parent ActionMap if the binding is not locally defined.

 public DowngradeActionMap getParent() 
{
    return parent;
}

Returns this ActionMap's parent.

 public Object[] keys() 
{
    return actionList.toArray();
}

Returns the Action names that are bound in this ActionMap.

 public  void put(Object key,
    Action action) 
{
    if (action == null)
    {
      remove(key);
    }
    else
    {
      if (actionMap.containsKey(key))
      {
        remove(key);
      }
      this.actionMap.put(key, action);
      this.actionList.add (key);
    }
}

Adds a binding for key to action. If action is null, this removes the current binding for key.

In most instances, key will be action.getValue(NAME).

 public  void remove(Object key) 
{
    actionMap.remove(key);
    actionList.remove(key);
}

Removes the binding for key from this ActionMap.

 public  void setParent(DowngradeActionMap map) 
{
    this.parent = map;
}

Sets this ActionMap's parent.

 public int size() 
{
    return actionMap.size();
}

Returns the number of bindings.
