Satisfaction
============

[](#satisfaction)

Satisfaction is a PHP implementation of the Specification pattern for DDD.

[![Build Status](https://camo.githubusercontent.com/35bd0fdc939eb3bd1e0dab56fdee5c453d988633cec027dc4be421598efa922d/68747470733a2f2f7472617669732d63692e6f72672f6d6178696d65636f6c696e2f736174697366616374696f6e2e737667)](https://travis-ci.org/maximecolin/satisfaction)

Purpose
-------

[](#purpose)

The aim of the specification pattern is to write domain specifications in reusable classes instead of dispatching domain rules conditons in all your project.

Installation
------------

[](#installation)

```
composer require maximecolin/satisfaction

```

Usage
-----

[](#usage)

### Simple example

[](#simple-example)

My model :

```
class Article
{
	public $published = false;
	public $publishedAt;
}
```

My specification :

```
use Satisfaction\CompositeSpecification;

class PublishedArticle extends CompositeSpecification
{
	public function isSatisfiedBy($article)
	{
		return $article->published === true && $article->publishedAt isSatisfiedBy($article)) {
	// Do something
}
```

### Or, And, Not

[](#or-and-not)

You can chain specifications with "or", "and" or "not" condition.

```
// If both foo and bar are satified
if ((new FooSpecification())->andX(new BarSpecification())->isSatifiedBy($object)) {
	// Do something
}
```

```
// If foo is satisfied or bar is not
if ((new FooSpecification())->orX((new BarSpecification())->not())->isSatifiedBy($object)) {
	// Do something
}
```
