This pattern is ideal where you want to isolate your application from the implementation of the concrete classes. For example if you wanted to overlay Delphi's VCL with a common VCL layer for both 16 and 32 bit applications, you might start with the abstract factory as a base....
In this tutorial, we'll go through an example and implementation of the Factory Method Design Pattern in Python, alongside the motivation and definition.
There is a section to introduce the Factory Pattern, I think it is the best practical example for this pattern which I have read. So I code it according the example, made little modification and added some annotation, then now share with you guys. Example from: Api Design For C++, Mart...
Design Patterns: Factory Method, Factory Method - Define an interface for creating an object, but let subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses. To name the method more descriptively, it c
