Template模式

在面向对象系统的分析与设计过程中经常会遇到这样一种情况：对于某一个业务逻辑（算法实现）在不同的对象中有不同的细节实现，但是逻辑（算法）的框架是相同的。Template提供了这种情况的实现框架。

Template.h

//Template.h
#ifndef _TEMPLATE_H_
#define _TEMPLATE_H_

class AbstractClass
{
public:
	virtual ~AbstractClass();
	void TemplateMethod();
protected:
	virtual void PrimitiveOperation1() = 0;
	virtual void PrimitiveOperation2() = 0;
	AbstractClass();
private:
};

class ConcreteClass1:public AbstractClass
{
public:
	ConcreteClass1();
	~ConcreteClass1();
protected:
	void PrimitiveOperation1();
	void PrimitiveOperation2();
private:
};

class ConcreteClass2:public AbstractClass
{
public:
	ConcreteClass2();
	~ConcreteClass2();
protected:
	void PrimitiveOperation1();
	void PrimitiveOperation2();
private:
};
#endif //~TEMPLATEH

#include "Template.h"
#include <iostream>
using namespace std;


AbstractClass::AbstractClass()
{

}
AbstractClass::~AbstractClass()
{

}
void AbstractClass::TemplateMethod()
{
	this->PrimitiveOperation1();
	this->PrimitiveOperation2();
}

ConcreteClass1::ConcreteClass1()
{

}
ConcreteClass1::~ConcreteClass1()
{

}
void ConcreteClass1::PrimitiveOperation1()
{
	cout<<"ConcreteClass1...PrimitiveOperation1"<<endl;
}
void ConcreteClass1::PrimitiveOperation2()
{
	cout<<"ConcreteClass1...PrimitiveOperation2"<<endl;
}

ConcreteClass2::ConcreteClass2()
{

}
ConcreteClass2::~ConcreteClass2()
{

}
void ConcreteClass2::PrimitiveOperation1()
{
	cout<<"ConcreteClass2...PrimitiveOperation1"<<endl;
}
void ConcreteClass2::PrimitiveOperation2()
{
	cout<<"ConcreteClass2...PrimitiveOperation2"<<endl;
}

#include "Template.h"

#include <iostream>
using namespace std;


int main(){
	AbstractClass* p1 = new ConcreteClass1();
	AbstractClass* p2 = new ConcreteClass2();

	p1->TemplateMethod();
	p2->TemplateMethod();

    return 0;
}
