1、构建基本类的抽象
#include <iostream>
class IComponent
{
public:
virtual void Operate()=0;
private:
};
2、构建基本类
class Component:public IComponent
{
public:
void Operate() override {
std::cout << "基础操作..."<<std::endl;
}
private:
};
3、构建装饰器类
class Decorate:public IComponent
{
private:
IComponent * m_component;
public:
Decorate(IComponent * component){
m_component = component;
}
void Operate() override{
std::cout << "操作前处理..." << std::endl;
m_component->Operate();
std::cout << "操作后处理..." << std::endl;
}
private:
};
4、调用：
class Decorate:public IComponent
{
private:
IComponent * m_component;
public:
Decorate(IComponent * component){
m_component = component;
}
void Operate() override{
std::cout << "操作前处理..." << std::endl;
m_component->Operate();
std::cout << "操作后处理..." << std::endl;
}
private:
};
