Python Design Patterns - Abstract Factory - The abstract factory pattern is also called factory of factories. This design pattern comes under the creational design pattern category. It provides one of the best ways to create an object.
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. ...
This factory is also called as factory of factories. This type of design pattern comes under creational pattern In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. Each generated factory can give the objects as ...
Factories The Factory pattern is powerful. It provides us with a framework for instantiating classes dynamically at run time according to the logic of the program. Let’s take a look at a simple example. (If you already know the Factory pattern, you may choose to skip this section.) Figure...
Abstract Factory pattern adds another layer of abstraction for Factory pattern. If we compare Abstract Factory with Factory, it is pretty obvious that a new layer of abstraction is added. Abstract Factory is a super-factory which creates other factories. We can call it “Factory of factories”....
Abstract Factory Pattern VS Factory Method/Simple Factory Pattern Abstract Factory Pattern: It providesdifferent kind of Factories, each provide a particular kind of related objects. Factory Method/Simple Factory Pattern: It providesone kind on objects only. ...
Luke Church watched the API usability presentation and contacted me with a question about a point I made regarding the factory design pattern and usability.One thing that I probably didn’t make clear in the presentation is that the difficulties with the factory design pattern are greatest for op...

We’ll be focusing on a family of design patterns we call Factory Patterns. The group includes the Simple Factory, Factory Method and Abstract Factory patterns:Simple Factory: Strictly speaking, it’s not a design pattern, but a technique we use very often. It encapsulates the object ...
The Factory Method defines an interface for creating objects, but lets subclasses decide which classes to instantiate. Injection molding presses demonstrate this pattern. Manufacturers of plastic toys process plastic molding powder, and inject the plastic into molds of the desired shapes. The class of...
