[PDF] abstract factory vs factory method

The main difference between a “factory method” and an “abstract factory” is that the factory method is a single method, and an abstract factory is an object. The factory method is just a method, it can be overridden in a subclass, whereas the abstract factory is an object that has multiple factory methods on it.

  • When would you use abstract factory over factory method?

    The idea behind the Factory Method pattern is that it allows for the case where a client doesn't know what concrete classes it will be required to create at runtime, but just wants to get a class that will do the job while Abstract Factory pattern is best utilized when your system has to create multiple families of 21 avr. 2011

  • What is the difference between factory pattern and factory method pattern?

    The intent of the factory method pattern is different from the simple factory. The factory method pattern is a software design pattern but the simple factory is like a programming idiom. The factory method pattern provides an abstraction/interface for creating an object. And the job must be done by a subclass.

  • Is abstract factory useful?

    Abstract Factory pattern is useful for creating multiple families (or factories) of related objects so that any specific object can be created at runtime from any of the concrete factory classes.
  • Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.
