抽象工廠模式

抽象工廠針對產品族，不針對產品等級結構

產品族：同一產地同一個廠商，功能不同。

產品等級結構：功能相同，但是產地和廠商不同。

class AbstractApple { public:virtual void showName() = 0; }; class ChApple : public AbstractApple { public:virtual void showName(){cout << "Ch Apple." << endl;} }; class USAApple : public AbstractApple { public:virtual void showName(){cout << "USA Apple." << endl;} }; class JpApple : public AbstractApple { public:virtual void showName(){cout << "Jp Apple." << endl;} };class AbstractBanana { public:virtual void showName() = 0; }; class ChBanana : public AbstractBanana { public:virtual void showName(){cout << "Ch Banana." << endl;} }; class USABanana : public AbstractBanana { public:virtual void showName(){cout << "USA Banana." << endl;} }; class JpBanana : public AbstractBanana { public:virtual void showName(){cout << "Jp Banana." << endl;} }; class AbstractPear { public:virtual void showName() = 0; }; class ChPear : public AbstractPear { public:virtual void showName(){cout << "Ch Pear." << endl;} }; class USAPear : public AbstractPear { public:virtual void showName(){cout << "USA Banana." << endl;} };class JpPear : public AbstractPear { public:virtual void showName(){cout << "Jp Pear." << endl;} };class AbstractFactory { public:virtual AbstractApple* createApple() = 0;virtual AbstractBanana* createBanana() = 0;virtual AbstractPear* createPear() = 0; };class ChFactory : AbstractFactory { public:virtual AbstractApple* createApple(){return new ChApple();}virtual AbstractBanana* createBanana(){return new ChBanana();}virtual AbstractPear* createPear(){return new ChPear();} }; class USAFactory : AbstractFactory { public:virtual AbstractApple* createApple(){return new USAApple();}virtual AbstractBanana* createBanana(){return new USABanana();}virtual AbstractPear* createPear(){return new USAPear();} }; class JpFactory : AbstractFactory { public:virtual AbstractApple* createApple(){return new JpApple();}virtual AbstractBanana* createBanana(){return new JpBanana();}virtual AbstractPear* createPear(){return new JpPear();} };
