org.perfectjpattern.core.api.creational.factorymethod
Interface IFactoryMethod<T>

Type Parameters:

T - Type of elements created.

public interface IFactoryMethod<T>

Factory Method Design Pattern: Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses. (Gamma et al, Design Patterns)

Responsibility Abstract definition of the "Creator":

• Declares the factory method, which returns an object of type Product.
• Creator may also define a default implementation of the factory method that returns a default ConcreteProduct object. may call the factory method to create a Product object.

Example usage:

 import org.perfectjpattern.core.api.creational.factorymethod.*;
       
  //
  // Example of Factory Method subtype that creates Product with a
  // name parameter. 
  //
  public IProductFactory
  extends IFactoryMethod<Product>
  {
      //--------------------------------------------------------------------
      // public
      //--------------------------------------------------------------------
      public void
      setName(String aName);          
  }
