/**

* Abstract Factory pattern

* Purpose:

* to create series of related or dependant objects without specifying their concrete classes,

* usually the created classes all implement the same interface. The client of the abstract

* factory does not care about how these objects are created, he just knows they go together.

* Sometimes also known as "Kit" in a GUI libraries.

* This design pattern implements the Dependency Inversion Principle since

* it is the concrete subclass which creates concrete components.

* In this case, the abstract factory is a contract for creating some components

* for the web. There are two components : Text and Picture. There is two ways

* of rendering : HTML or JSON.

* Therefore 4 concretes classes, but the client just need to know this contract

* to build a correct http response (for a html page or for an ajax request)

abstract class AbstractFactory

{

/**

* Creates a text component

* @param string $content

* @return Text

abstract public function createText($content);

/**

* Creates a picture component

* @param string $path

* @param string $name

* @return Picture

abstract public function createPicture($path, $name = '');
