C++设计模式---适配器模式（高屋建瓴）

#include <iostream>
using namespace std;
class Target {
 public:
  Target() {}
  virtual ~Target() {}
  virtual void Request() {
    cout << "Target::Requeast"<<endl;
  }
};
class Adaptee {
 public:
  void SpecificRequest() {
    cout << "Adaptee::SpecificRequest" << endl;
  }
};
class Adapter : public Target {
 public:
  Adapter() : adaptee_(new Adaptee) {}
  ~Adapter() {
    if (adaptee_ != NULL) {
      delete adaptee_;
      adaptee_ = NULL;
    }
  }
  void Request() {
    adaptee_->SpecificRequest();
  }
 private:
  Adaptee *adaptee_;
};

int main() {
  Target *target = new Adapter();
  target->Request();
  delete target;
  target = NULL;
  return 0;
}

输出结果：
Adaptee::SpecificRequest
