Abstract factory design pattern for animal. Abstract factory patterns work around a super factory which creates other factories. Animal animal factorygetanimal. Imho this is the factory method pattern. Free source code and uml.
It returns an implementation of animalfactory the implementation is a concrete factory. If the requirements for this animal factory is that i need a wild animal. Encapsulate object creation in a separate factory object. I think abstract factory usually relies on a two steps use.
That is define an interface abstractfactory for creating objects and implement the interface. Animalfactory factory xxxgetfactoryanimaltype. The legs of that animal should be four and the weight should be less than 4kg. In abstract factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.
A class delegates object creation to a factory object instead of creating objects directly. The animal factory would be abstract to the outside world. The getfactorymethod can be a static method an instance method. Lets consider an example.
Abstract factory pattern is almost similar to factory pattern is considered as another layer of abstraction over factory pattern. The abstract factory design pattern describes how to solve such problems. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. The first thing the abstract factory pattern suggests is to explicitly declare interfaces for each distinct product of the product family eg chair sofa or coffee table.
The abstract factory pattern is designed to build objects grouped in families without having to know the concrete class needed to create the object. Available in seamless repeat royalty free. Then you can make all variants of products follow those interfaces. Abstract factory design pattern is one of the creational pattern.
