今天由于要寫一些東西，遇到了需要把成員函數(shù)作為函數(shù)參數(shù)的問題
總結(jié)有以下幾個辦法:
1.使用類的靜態(tài)成員:
????? 最簡單的.只是這種辦法與使用普通函數(shù)沒有什么區(qū)別
2.模板的方法
?
1???template<class??T>???
2???void??Call(T*?ptr,void(T::*MenFn)())???
3???{???
4??????(ptr->*MenFn)();???
5???}???
???
?1?
class?MyClass
?2?
{
?3?
public:
?4?
????void?Call()
?5?
????{
?6?
???????
?7?
????}
?8?
};
?9?
10?
MyClass?cs;
11?
Call(&cs,&MyCall::Call); 3.??虛擬繼承的方法
?1?
class?Base
?2?
{
?3?
public:
?4?
????virtual?void?Call()?=?0;
?5?
};????
?6?
?7?
class?SubClass?:public?Base
?8?
{
?9?
public:
10?
????void?Call(){}
11?
};
12?
?
13?
void?Call(Base?*ptr)
14?
{
15?
????ptr->Call();
16?
}? 4.use boost.
?
?1
#include???<boost/bind.hpp>???
?2#include???<iostream>???
?3using???namespace???std;???
?4struct???MyClass???
?5
{???
?6
????void??Print(const?char*?str)???
?7
????{???
?8????????cout<<"holle?"<<str<<endl;???
?9
????}???
10
};
11
12template<class?_Fun>???
13void?CallBackFun(_Fun?a,const?char*?str)???
14{???
15????t(n);???
16}???
17?
18int???main()???
19{???
20????MyClass?mc;
21????CallBackFun(boost::bind(boost::mem_fn(&MyClass::Print),&mc,_1),"world")
22????return??1;???
23}???
24 ? 5.使用靜態(tài)成員函數(shù)或者聯(lián)合體模擬之
1?union
2?{
3?????void(G_CALL?ParticleSystem::*PhysicsThreadFun)(void?*arg);
4?????ThreadFun?f;
5?}fn;?
6?fn.PhysicsThreadFun?=?&ParticleSystem::PhysicsThreadFun;
7?thread_id?=?CreateThread(fn.f,&ps);
6.也許.
??????對loki庫不太熟悉也許上面也有答案吧
