桥接模式网上都讲得很复杂，我总结一下就是一句话：
如果多个维度变化，每个维度都有一个基类，嗯，就这样
#include <iostream>
using namespace std;
class Os {
public:
virtual void SetOs() = 0;
};
class LinuxOs : public Os {
public:
void SetOs() {
cout<< "set linux" << endl;
}
};
class WindowsOs : public Os {
public:
void SetOs() {
cout<< "set windows" << endl;
}
};
class MacOs : public Os {
public:
void SetOs() {
cout<< "set mac" << endl;
}
};
class Computer {
public:
Computer(Os* s) : os_(s) {
}
virtual ~Computer() {
if (os_) {
delete os_;
}
os_ = NULL;
}
public:
virtual void InstallOs() = 0;
protected:
Os* os_;
};
class DellComputer : public Computer {
public:
DellComputer(Os* s) : Computer(s) {
}
public:
void InstallOs() {
cout<< "DellComputer:" << endl;
os_->SetOs();
}
};
class MacComputer : public Computer{
public:
MacComputer(Os* s) : Computer(s) {
}
public:
void InstallOs() {
cout<< "MacComputer:" << endl;
os_->SetOs();
}
};
class IbmComputer : public Computer{
public:
IbmComputer(Os* s) : Computer(s) {
}
public:
void InstallOs() {
cout<< "IbmComputer:" << endl;
os_->SetOs();
}
};#include "main.h"
using namespace std;
int main(int argc, char* argv[]) {
Computer* c = new DellComputer(new WindowsOs);
c->InstallOs();
Computer* c2 = new MacComputer(new MacOs);
c2->InstallOs();
Computer* c3 = new IbmComputer(new LinuxOs);
c3->InstallOs();
}
