as3中Vector中对象之排序

假如Vector中的对象是Boarder类，此类中两个属性 name,scores

 public class Boarder
	{
	
		private var _name:String;
		private var _score:int;
		public function Boarder(name:String,score:int)
		{
			_name = name;
			_score = score;
		}

		public function get score():int
		{
			return _score;
		}

		public function set score(value:int):void
		{
			_score = value;
		}

		public function get name():String
		{
			return _name;
		}

		public function set name(value:String):void
		{
			_name = value;
		}

	}

下面要按照score排序，以下为倒序排

		private function sortScores(x:Boarder,y:Boarder):int{
			if(x.score > y.score){
				return -1;
			}else if(x.score < y.score ){
				return 1;
			}else{
				return 0;
			}
		}

已知集合sortedscoreVec ，那么关键的一句
sortedscoreVec = sortedscoreVec.sort(sortScores);
即可将sortedscoreVec 按照score从高到低排序
