隨意寫的，主要用作程式碼練習，防止程式碼生疏，敬請見諒！

本意是能夠寫成一個多用途的代理模式，結果還是寫廢了，其他方面來說，沒有時間重整它，有的寫法是沒有太大意義的。期望有點價值吧

首先放一個代理模式的講解，個人覺得寫得不錯，如果你是尋求代理模式的用法用途的話，值得一看：

//ProxyPattern.h

#pragma once
#include <iostream>
#include <typeinfo>
#include <string>
template<typename ReturnValue,typename T,typename T2>
class IMutiUser
{
public:
    virtual	ReturnValue (T)(...)= 0;
	virtual ReturnValue GetReturnType()const = 0;
};
template<typename ReturnValue, typename T,typename T2>
class IMutiProxy :public IMutiUser<ReturnValue,T,T2>
{
protected:
	T2*  mMImpl;
public:
	virtual ReturnValue (T)(...) override;
	virtual ReturnValue GetReturnType()const override;
};
template<typename ReturnValue, typename T,typename T2>
ReturnValue IMutiProxy<ReturnValue,T,T2>::T(...)
{
	mMImpl = new T2();
	if (mMImpl != nullptr)
	{
		std::cout << "Show Something of IMutiProxy!" << std::endl;
		mMImpl->T();
	}
	ReturnValue temp= NULL;
	return temp;
}
template<typename ReturnValue, typename T,typename T2>
ReturnValue IMutiProxy<ReturnValue, T,T2>::GetReturnType()const
{
	ReturnValue temp=NULL;
	return temp;
}
template<typename ReturnValue, typename T,typename T2>
class IMutiImplement :public IMutiUser<ReturnValue,T,T2>
{
public:
	virtual ReturnValue(T)(...) override;
	virtual ReturnValue GetReturnType() const override;
};
template<typename ReturnValue, typename T,typename T2>
ReturnValue IMutiImplement<ReturnValue, T,T2>::T(...)
{
	std::cout << "show something!" << std::endl;
	std::cout << "You could dispose something for custom function ." << std::endl;
	ReturnValue temp=NULL;
	return temp;
}
template<typename ReturnValue, typename T,typename T2>
ReturnValue IMutiImplement<ReturnValue, T,T2>::GetReturnType() const
{
	ReturnValue temp=NULL;
	return temp;
}

 

#include "ProxyPattern.h"
int show(int number)
{
	std::cout << "Current Number is :" + number << std::endl;
	return 1;
}
int main(...)
{
	int(*func)(int b);
	func = show;
	IMutiUser<int, decltype(func),IMutiImplement<int,decltype(func),void>>* temp = new IMutiProxy<int, decltype(func),IMutiImplement<int, decltype(func),void>>();
	temp->T();
	temp->GetReturnType();
	system("pause");
	return 0;
}
