NullBudgetGameOption.as

public class NullBudgetGameOption 
{
	
	public function NullBudgetGameOption()
	{
	} 
		
	public function select():void { }

	public function deselect():void { }
		
	public function enable():void { }
		
	public function disable():void { }

	public function get selectedSignal():Signal
	{
		return null;
	}

	public function get deselectedSignal():Signal
	{
		return null;
	}
		
}
