Adapter模式
分为类模式和对象两种
类模式public继承接口,private继承实现
Adapter.h
#ifndef _ADAPTER_H
#define _ADAPTER_H
#include <iostream>
using namespace std;
class Target
{
public:
Target() {}
virtual ~Target() {}
virtual void Request() {
cout << "Target:Request" << endl;
}
};
class Adaptee
{
public:
Adaptee() {}
~Adaptee() {}
void SpecificRequest() {
cout << "Adaptee:SpecificRequest" << endl;
}
};
class Adapter : public Target,private Adaptee
{
public:
Adapter() {}
~Adapter() {}
void Request() {
SpecificRequest();
}
};
#endif // _ADAPTER_H
Adapter.cpp
#include "Adapter.h"
int main()
{
Adapter adapter;
adapter.Request();
return 0;
}
编译:make Adapter
对象模式使用委托(组合)来实现,这种写法应该见过挺多了
Adapter.h
#ifndef _ADAPTER_H
#define _ADAPTER_H
#include <iostream>
using namespace std;
class Target
{
public:
Target() {}
virtual ~Target() {}
virtual void Request() {
cout << "Target:Request" << endl;
}
};
class Adaptee
{
public:
Adaptee() {}
~Adaptee() {}
void SpecificRequest() {
cout << "Adaptee:SpecificRequest" << endl;
}
};
class Adapter : public Target
{
public:
Adapter(Adaptee* ade) {
_ade = ade;
}
~Adapter() {}
void Request() {
_ade->SpecificRequest();
}
private:
Adaptee* _ade;
};
#endif // _ADAPTER_H
Adapter.cpp:
#include "Adapter.h"
int main()
{
Adaptee* ade = new Adaptee;
Target* adt = new Adapter(ade);
adt->Request();
return 0;
}
编译:make Adapter
