As per as a2D vectoris concerned it's avector of a 1D vector. But what we do in sorting a 1D vector like, sort(vector.begin(),vector.end()); We can't do the same for a 2D vector without any user-defined comparator function, as it will merely sort based on the first element ...

sort方法就像是一个超级管家,专门负责把vector这个小盒子里的东西按照一定的顺序排列好。比如说,你把一堆乱七八糟的数字放进vector里,就像把一堆乱哄哄的小玩具扔在盒子里,sort方法这个管家就能迅速地把这些数字按照从小到大或者从大到小的顺序整整齐齐地排好,就像把玩具按照大小或者颜色整整齐齐地摆放好一样。
private function sortNum(x:Number, y:Number):Number{ if (x < y){ return 1; } else if (x > y){ return -1; } else{ return 0; } } 调用$back.sort(sortRank); 注 : $back 是 vector.<RankPlayerModel>类型的 因为Vector 比 Array 的 性能要高 , 但是 Vector 没有 Array 的sorton功能...
