Iterator Design Pattern In Python from coursegalaxy.com
Subclasses can override this method to change the class of objects that will be created. The abstract factory method provides developers with a mechanism to create closely related objects without specifying their concrete class. There are various creational design patterns like a factory, abstract factory, builder, prototype, and singleton methods.

The abstract factory pattern is also called factory of factories. Most of them are formed and named by gang of four. An abstract factory is a generative design pattern that allows you to create families of related objects without getting attached to specific classes of created objects.

In this section, we will discuss the abstract factory method. A car frame should accept any tire that can go on the same line. Factory method defines a method, which should be used for creating objects instead of direct constructor call ( new operator). You code will still work without them. 1) decouple the client code.

The fdp is based on a single function written. Most of them are formed and named by gang of four. Here, objects are created without exposing the logic to the client. You use this pattern when you want to return one of several related classes of objects, each of which can return several different objects on request. 1) decouple the.

This pattern is best suited when one wishes to create multiple categories of an object by abstracting its implementation. It includes an interface, which is responsible for creating objects related to factory.
