Creational Design Pattern

• Prototype
• Abstract Factory

Prototype

• Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.
• Co-opt one instance of a class for use as a breeder of all future instances.
• The new operator considered harmful.

Abstract Factory

Abstract Factory classes are often implemented with Factory Methods, but they can also be implemented using Prototype.
Abstract Factory might store a set of Prototypes from which to clone and return product objects.

• Factory Method: creation through inheritance.
• Prototype: creation through delegation.
• Virtual constructor: defer choice of object to create until run-time.
