Reading Group Head First Design Patterns

This project is a result of the reading group about design patterns. Starting the 6th of june, every week there will be a meetup and a new design pattern will be added to this repo.

Strategy Pattern (06/06/2019)

The Strategy Pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

Observer Pattern (13/06/2019)

The Observer Pattern defines a one-to-many dependency between objects so that when one object changes state, all of its dependents are notified and updated automatically.

Decorator Pattern (20/06/2019)

The Decorator Pattern attaches additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality.

Factory Pattern (27/06/2019)

The Factory Method Pattern: defines an interface for creating an object, but lets subclasses decide which class to instantiate. Factory Method lets a class defer instantiation to subclasses.

The Abstract Factory Pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes.

Singleton Pattern (04/07/2019)

The Singleton Pattern ensures a class has only one instance, and provides a global point of access to it.

Command Pattern (11/07/2019)

The Command Pattern encapsulates a request as an object, thereby letting you parameterize other objects with different requests, queue or log requests, and support undoable operations.

Adapter & Facade Pattern (18/07/2019)

The Adapter Pattern converts the interface of a class into another interface clients expect. Lets classes work together that couldn't otherwise because of incompatible interfaces.

The Facade Pattern provides a minified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.

Template Method Pattern (25/07/2019)

The Template Method Pattern defines the skeleton of an algorithm in a method, deferring some steps to subclasses. Template Method lets the subclasses redefine certain steps of an algorithm without changing the algorithm's structure.

Iterator and Composite Patterns (29/08/2019)

The Iterator Pattern provides a way to access the elements of an aggregate object sequentially without expoing its underlying representation.

The Composite Pattern allows you to compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly.

The State Pattern (19/09/2019)

The State Pattern allows an object to alter its behavior when its internal state changes. The object will appear to change its class.

Proxy Pattern (26/09/2019)

The Proxy Pattern provides a surrogate or placeholder for another object to control access to it.

Hosted by: Maxime Orione

Next Host: Alexandre Vettas

Compound Pattern (17/10/2019 & 24/10/2019)

A Compound Pattern combines two or more patterns into a solution that solves a recurring or general problem.
