map管理成员函数指针

转自：http://bbs.youkuaiyun.com/topics/290032347

概括：将成员函数指针名和同名的string类型的变量名进行绑定，插入到map中。
在使用时就可以通过找到string类型的变量名来使用同名的函数

#include "iostream"
#include "string"
#include "map"
using namespace std;

class test
{
public :
    void fun1() { cout<<"call test::fun1"<<endl; }
    void fun2() { cout<<"call test::fun2"<<endl; }
    void fun3() { cout<<"call test::fun3"<<endl; }

    test()
    {
        m_mapFun["test::fun1"] = &test::fun1;
        m_mapFun["test::fun2"] = &test::fun2;
        m_mapFun["test::fun3"] = &test::fun3;
    }

    void call(string strfun)
    {
        if (m_mapFun.find(strfun) == m_mapFun.end())
            cout<<"no function : "<<strfun<<endl;
        else
            (this->*m_mapFun[strfun])();
    }
protected :
    typedef void (test::*mfun)();
    map<string, mfun> m_mapFun;
};

int main()
{
    test t;
    t.call("test::fun1");
    t.call("test::fun2");
    t.call("test::fun3");
    t.call("test::fun4");
    return 0;
}

-----------------
结果：
call test::fun1
call test::fun2
call test::fun3
no function : test::fun4
