c++设计模式之适配器模式
cpp
// SwitchInterface.h
#ifndef SWITCH_INTERFACE_H
#define SWITCH_INTERFACE_H
class SwitchInterface {
public:
virtual void login(const std::string& username, const std::string& password) = 0;
virtual void configure(const std::string& config) = 0;
virtual ~SwitchInterface() {}
};
#endif // SWITCH_INTERFACE_H
SwitchInterface 定义了监控系统期望的统一接口，所有的交换机设备都需要实现这个接口。
1.2 定义具体设备类
cpp
// S5730.h
#ifndef S5730_H
#define S5730_H
#include <iostream>
class S5730 {
public:
void loginS5730(const std::string& username, const std::string& password) {
std::cout << "S5730 login with username: " << username << std::endl;
}
void configureS5730(const std::string& config) {
std::cout << "Configuring S5730 with: " << config << std::endl;
}
};
#endif // S5730_H
cpp
// S12700.h
#ifndef S12700_H
#define S12700_H
#include <iostream>
class S12700 {
public:
void loginS12700(const std::string& username, const std::string& password) {
std::cout << "S12700 login with username: " << username << std::endl;
}
void configureS12700(const std::string& config) {
std::cout << "Configuring S12700 with: " << config << std::endl;
}
};
#endif // S12700_H
1.3 定义适配器
cpp
// S5730Adapter.h
#ifndef S5730_ADAPTER_H
#define S5730_ADAPTER_H
#include "SwitchInterface.h"
#include "S5730.h"
class S5730Adapter : public SwitchInterface {
private:
S5730 s5730;
public:
void login(const std::string& username, const std::string& password) override {
s5730.loginS5730(username, password);
}
void configure(const std::string& config) override {
s5730.configureS5730(config);
}
};
#endif // S5730_ADAPTER_H
cpp
// S12700Adapter.h
#ifndef S12700_ADAPTER_H
#define S12700_ADAPTER_H
#include "SwitchInterface.h"
#include "S12700.h"
class S12700Adapter : public SwitchInterface {
private:
S12700 s12700;
public:
void login(const std::string& username, const std::string& password) override {
s12700.loginS12700(username, password);
}
void configure(const std::string& config) override {
s12700.configureS12700(config);
}
};
#endif // S12700_ADAPTER_H
1.4 使用适配器
cpp
// Main.cpp
#include "S5730Adapter.h"
#include "S12700Adapter.h"
int main() {
SwitchInterface* switch1 = new S5730Adapter();
switch1->login("admin", "password123");
switch1->configure("Set interface GigabitEthernet0/0/1 to up");
SwitchInterface* switch2 = new S12700Adapter();
switch2->login("admin", "password456");
switch2->configure("Set interface GigabitEthernet0/0/2 to down");
delete switch1;
delete switch2;
return 0;
}
