std :: for_each + break [英] std::for_each + break

问题描述

嗨


我想给一些带有谓词的库类的模板方法，

我把它放到那个方法的std :: for_each中。如何用谓词打破

std :: for_each？（例如在特殊的

情况下使用olny，正如我所知）


谢谢

解决方案

也许你会更好地服务于std :: find_if

谓词，我把它放到std :: for_each那个方法中。怎么回事

break带谓词的std :: for_each？（例外情况是使用

你不能。这正是for_each的重点。

Perhaps you would be better served by std::find_if
