Chain of responsibility
Function
Establish the line that must carry the messages for the objects to perform the indicated task.

Command
Function
Encapsulate an operation in an object, allowing it to be executed without the need to know its content.
Iterator
Function
According to the Gang of Four book, we can perform tours on composite objects regardless of their implementation.
Interpreter
Function
Define a grammar for a given language, as well as the tools needed to interpret it.
Mediator
Function
Define an object that coordinates communication between others of different kinds, but that functions as a whole.
Memento
Function
Return to previous system states.
Observer
Function
Define a one-to-many dependency between objects, so that when one changes state, all the objects that depend on it are automatically notified and updated.
State
Function
Altering the internal behaviour of an object.
Strategy
Function
Define a family of algorithms, encapsulated and interchangeable. The strategy allows the algorithm to vary independently of the customers using it.
Template method
Function
Redefine subclasses by following certain steps of an algorithm without changing the structure of the algorithm.
Visitor
Function
Representing a function to be performed by the elements of the object's structure, it also allows defining a new function without changing the classes of the elements in which it operates.
