Jak používám anemický model.

anemic.php

<?php

class ArticleIdentification extends Article, Identification
{
}


class ArticleIdIdentification implements ArticleIdentification
{
	function __construct($num)
	{}
	
	function getIdentKey()
	{}

}

{
	function __construct($str)
	{}
	
	function getIdentKey()
	{}

}


class ArticleNew implements Article
{
	function __construct($name, $content, User $author)
	{}
	
	function getName()
	{}

	function getContent()
	{}

	function getAuthor()
	{}
}



class ArticleEntry implements Article
{
	function __construct(ArticleIdentification $id, $name, $content, User $author)
	{}
