请教multimap 的问题

hnuhwk 2007-10-31 10:24:16

我写了一个小程序
用multimap来排序 multimap<int,Stop*>* Passstop;
关键码是int型的
而另外一个是指针
指向一个对象
没有查找时插入可以成功，仅仅是有警告
在通过匹配关键码来得到一个特定的stop*时（我也不太清楚是否可以得到一个stop*,是否multimap里面存储了我插进去的stop*）不仅警告了，连编译都通不过
错误如下：:\program files\microsoft visual studio\vc98\include\map(206) : warning C4786: 'std::reverse_bidirectional_iterator<std::_Tree<int,std::pair<int const ,Stop *>,std::multimap<int,Stop *,std::less<int>,std::allocator<Stop *> >::_Kfn,std::less<int>,st
