C + +, Java implementations of the abstract factory model

1. Abstract Factory mode UML

1 Total UML for Abstract Factory mode

2. C + + implementation

The C + + implementation class Diagram Is:

2 Total C + + implementation class diagram for abstract Factory mode

Where the implementation code for Abstractfactory Is:

1 //abstract Factory class base class. 2 classabstractfactory3 {4  public:5 abstractfactory ();6~abstractfactory ();7 8     //Create an abstract factory method for a specific product. 9     //creates a Class A object. Ten     VirtualProductA * Createproducta () =0; one  a     //Create a Class B product object.  -     VirtualPRODUCTB * CREATEPRODUCTB () =0; -};

The implementation code for the Concretefactorya is:

1 classConcreteFactory1:2      publicabstractfactory3 {4  public:5 ConcreteFactory1 ();6~ConcreteFactory1 ();7 8     //creates an abstract factory method for ConcreteProductA1. 9ProductA *createproducta ();Ten  one     //creates an abstract factory method for ConcreteProductA1.  aPRODUCTB *CREATEPRODUCTB (); -  -};//End Class Concretefactorya the  -  -ProductA *concretefactory1::createproducta () - { +PRODUCTA * PA =NewConcreteProductA1 (); -     returnpa; +}//End Method Createproducta a  atPRODUCTB *CONCRETEFACTORY1::CREATEPRODUCTB () - { -PRODUCTB * PB =NewConcreteProductB1 (); -     returnpb; -}//End Method CREATEPRODUCTB

The ConcreteFactory2 code is similar to ConcreteFactory1 and is no longer listed.

3. Implementation of Java

The Java Implementation Class View Is:

Figure 3. Java implementation Class View of abstract Factory mode

Where the code for Abstractfactory is:

1 //Abstract Factory class. 2  public InterfaceAbstractfactory {3 4     //Create an abstract factory method for Class A Products. 5      public Abstractproducta createproducta ();6     7     //Create an abstract factory method for Class B Products. 8      public AbstractPRODUCTB CREATEPRODUCTB ();9     Ten}//End Interface Abstractfactory

The code for ConcreteFactory1 is:

1  public classConcreteFactory1ImplementsAbstractfactory {2 3     //creates an ConcreteProductA1 Object. 4 @Override5      publicproducta createproducta () {6         //TODO auto-generated Method Stub7         return NewConcreteProductA1 ();8}//End Method Createproducta9 Ten     //creates an ConcreteProductB1 Object.  one @Override a      publicPRODUCTB CREATEPRODUCTB () { -         //TODO auto-generated Method Stub -         return NewConcreteProductB1 (); the}//End Method CREATEPRODUCTB -  -}//End Class ConcreteFactory1

The code for ConcreteFactory2 is similar to ConcreteFactory1 and is no longer listed Here.
