Hi, The main difference between Abstract and Builder pattern is Abstract will return the instance directly while in Builder there will be one Director class which will instruct Builder class to build the different parts/properties of your object and finally retrieve the object. Sometimes I'll put the builder function into a base class -- which means that I have a builder function that is actually an abstract factory, which might itself use builder functions. An implementation of the Factory Method or Abstract Factory can include a implementation of the Builder pattern. Now for more detail: Builder A Builder encapsulates complex creation into a single method (or class). It works like so: The pattern is a system of two classes, the Creator and the ConcreteCreator.The Creator is an abstract class, and the ConcreteCreator is a subclass of that class.. 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. They are all Creational patterns and are complimentary. Abstract factory is used for creating a family of objects, which share a common interface. Note that in PizzaStore , the abstract method createPizza must be called somewhere from - lets say a method createLotsOfPizza . The Factory Method Design Pattern is named after the Factory Method.. The product class defines the type of the complex object that is to be generated by the builder pattern. The Factory Method pattern uses inheritance and relies on a subclass to handle the desired object instantiation. Builder, on the other hand, is concerned with building a single type of object. Garment Factory produce different kinds of clothes, On the other hand, Abstract Factory … Both the Abstract Factory and Factory design pattern are creational design pattern and use to decouple clients from creating objects they need, But there is a significant difference between Factory and Abstract Factory design pattern, Factory design pattern produces implementation of Products e.g. They vary in the context of their usage. Abstract factory and Builder, both help in creating objects and are as such part of the creational design patterns. Builder – This abstract base class defines all of the steps that must be taken in order to correctly create a product. The factory method is also about a class where abstract methods are overwritten, a core point is the caller of that method does not need to know the exact type of the created object. This pattern provides a specific way to encapsulate object creation from the client. Advantages. Abstract factory and Builder, both help in creating objects and are as such part of the creational design patterns. Many abstract factories that I've written use builder functions. method vs full class (object) factory method is just a method while abstract factory is an object . A factory can also be passed a Prototype instance to help it create the correct object. Factory Method Pattern Class Diagram: Figure 2: Factory Method Pattern In this example, instead of a Factory class to create the instances, the sub-classes of the Factory class decides which instance of the class is to be created. They vary in the context of their usage. It is a different level of abstraction, but the Factory Method helps to define differences between subclasses when they are created, while the Abstract Method may be concerned with deploying entirely unrelated (though similar) classes, as a whole.
