![]() * Concrete Products provide various implementations of the Product interface. Virtual std::string Operation() const = 0 The idea is to use a static member-function (static factory method) which creates. In this we create object without exposing the creation logic to client and the client use the same common interface to create new type of object. * The Product interface declares the operations that all concrete products must Factory method also known as a static class is a creational design pattern, i.e. In what way the elements of the pattern are related? Factory Method is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of.This example illustrates the structure of the Factory Method design pattern. While concrete classes are used during the object creation, the return type of the factory methods is usually declared as either an abstract class or an interface. Identification: Factory methods can be recognized by creation methods that construct objects from concrete classes. These objects will be accessed by inheriting their base class interface. ![]() It’s very useful when you need to provide a high level of flexibility for your code. The following code shows the basic template code of the abstract factory design pattern implemented using C: In the above abstract factory design pattern, the source code template client has two private fields that hold the instances of abstract product classes. ![]() ![]() Usage examples: The Factory Method pattern is widely used in C++ code. ![]()
