在C++中如何使用多态的容器？

Question

比如我想使用一个存放可调用对象的容器，可以同时容纳匿名函数，仿函数，函数指针和std::function,如何实现呢？

Answer 1

You just use std::function to wrap it up. As long as the call signatures of these anonymous functions, functors, function pointers and the like are the same, you can use std::function to save them and put them in a container. .

Answer 2

Use Boost.Any, a generic container
