如何复制spark Path

[feifeigrace]

我用Path画了一根曲线，我现在想复制这根曲线，应该怎么做？绘制曲线代码

private var shape:Path = new Path();
private var pathPoints:Vector.<Point>
private function mouseMove(event:MouseEvent):void
{
    pathPoints[pathPoints.length] = new Point(panel.container.canvas.mouseX, panel.container.canvas.mouseY);
    constructPath();
}

private function constructPath():void
		{
			var dataString = "M "+ pathPoints[0].x +" "+ pathPoints[0].y;
			for(var i:int=1; i< pathPoints.length; ++i)
			{
				var pt:Point = pathPoints[i];
				dataString += " L "+ pt.x +" "+pt.y;
			}
			shape.data = dataString;
		}

Path是什么类？哪个包里面的？
