 public AccessibleStateSet() 
{
        states = null;
}

Creates a new empty state set.

 public AccessibleStateSet(AccessibleState[] states) 
{
        if (states.length != 0) {
            this.states = new Vector(states.length);
            for (int i = 0; i <  states.length; i++) {
                if (!this.states.contains(states[i])) {
                    this.states.addElement(states[i]);
                }
            }
        }
}

Creates a new state with the initial set of states contained in the array of states passed in. Duplicate entries are ignored.

Parameters:

states - an array of AccessibleState describing the state set.

 public boolean add(AccessibleState state) 
{
        // [[[ PENDING:  WDW - the implementation of this does not need
        // to always use a vector of states.  It could be improved by
        // caching the states as a bit set.]]]
        if (states == null) {
            states = new Vector();
        }
        if (!states.contains(state)) {
            states.addElement(state);
            return true;
        } else {
            return false;
        }
}

Adds a new state to the current state set if it is not already present. If the state is already in the state set, the state set is unchanged and the return value is false. Otherwise, the state is added to the state set and the return value is true.

 public  void addAll(AccessibleState[] states) 
{
        if (states.length != 0) {
            if (this.states == null) {
                this.states = new Vector(states.length);
            }
            for (int i = 0; i <  states.length; i++) {
                if (!this.states.contains(states[i])) {
                    this.states.addElement(states[i]);
                }
            }
        }
}

Adds all of the states to the existing state set. Duplicate entries are ignored.

 public  void clear() 
{
        if (states != null) {
            states.removeAllElements();
        }
}

Removes all the states from the current state set.

 public boolean contains(AccessibleState state) 
{
        if (states == null) {
            return false;
        } else {
            return states.contains(state);
        }
}

Checks if the current state is in the state set.

 public boolean remove(AccessibleState state) 
{
        if (states == null) {
            return false;
        } else {
            return states.removeElement(state);
        }
}

Removes a state from the current state set. If the state is not in the set, the state set will be unchanged and the return value will be false. If the state is in the state set, it will be removed from the set and the return value will be true.

 public AccessibleState[] toArray() 
{
        if (states == null) {
            return new AccessibleState[0];
        } else {
            AccessibleState[] stateArray = new AccessibleState[states.size()];
            for (int i = 0; i <  stateArray.length; i++) {
                stateArray[i] = (AccessibleState) states.elementAt(i);
            }
            return stateArray;
        }
}

Returns the current state set as an array of AccessibleState

 public String toString() 
{
        String ret = null;
        if ((states != null) && (states.size()  > 0)) {
            ret = ((AccessibleState) (states.elementAt(0))).toDisplayString();
            for (int i = 1; i <  states.size(); i++) {
                ret = ret + ","
                        + ((AccessibleState) (states.elementAt(i))).
                                              toDisplayString();
            }
        }
        return ret;
}

Creates a localized String representing all the states in the set using the default locale.
