It’s especially useful when you need to create an object with lots of possible configuration options. Identification: The Builder pattern can be recognized in a class, which has a single creation method and several methods to configure the resulting object.

The quickest way to find dead code is to use a good IDE. Delete unused code and unneeded files. In the case of an unnecessary class, Inline Class or Collapse Hierarchy can be applied if a subclass or superclass is used. To remove unneeded parameters, use Remove Parameter.

How to Refactor. Make sure that you have simplified the existing algorithm as much as possible. Move unimportant code to other methods using Extract Method. The fewer moving parts in your algorithm, the easier it’s to replace. Create your new algorithm in a new method. Replace the old algorithm with the new one and start testing the program.Without refactoring it will eventually fail, thus refactoring may be considered an essential skill of any professional software engineer.

Facade. in Python. Facade is a structural design pattern that provides a simplified (but limited) interface to a complex system of classes, library or framework. While Facade decreases the overall complexity of the application, it also helps to move unwanted dependencies to one place.

Turns a request into a stand-alone object that contains all information about the request. This transformation lets you pass requests as a method arguments, delay or queue a request's execution, and support undoable operations.

Its objects can execute operations over various objects of different classes. You can use Visitor to execute an operation over an entire Composite tree. You can use Visitor along with Iterator to traverse a complex data structure and execute some operation over its elements, even if they all have different classes. Oh, mighty enzymes!

Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes. Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes. Each factory type corresponds to a ...Often fields are moved as part of the Extract Class technique. Deciding which class to leave the field in can be tough. Here is our rule of thumb: put a field in the same place as the methods that use it (or else where most of these methods are). This rule will help in other cases when a field is simply located in the wrong place.The mediator object plays the role of publisher, and the components act as subscribers which subscribe to and unsubscribe from the mediator’s events.

The Memento is a value object that acts as a snapshot of the originator’s state. It’s a common practice to make the memento immutable and pass it the data only once, via the constructor. The Caretaker knows not only “when” and “why” to capture the originator’s state, but also when the state should be restored.Singleton is a creational design pattern, which ensures that only one object of its kind exists and provides a single point of access to it for any other code.
