Dependency Resolver
===================

[](#dependency-resolver)

[![Build Status](https://camo.githubusercontent.com/d3cad2fe3903e8e0e280faf8a80ae382cdaaca3aca8189990b89bdf29b4db139/68747470733a2f2f7472617669732d63692e6f72672f6d617269616e6f2d6461676f7374696e6f2f446570656e64656e63795265736f6c7665722e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/mariano-dagostino/DependencyResolver)

This package allows to define a set of generic components that depends on other components. The DependencyResolver will then define the order of loading of those components.

Basic usage
-----------

[](#basic-usage)

```
use mdagostino\DependencyResolver\DependencyResolver;

$resolver = new DependencyResolver();
$resolver
  ->component('ITEM 1')->requires('ITEM 3', 'ITEM 4') // Item 1 requires item 3 and 4.
  ->component('ITEM 2')->requires('ITEM 1')           // Item 2 requires item 1.
  ->component('ITEM 3')                               // Item 3 doesn't have dependencies.
  ->component('ITEM 4');                              // Item 4 doesn't have dependencies.

$ordered = $resolver->resolveDependencies();
print_r($ordered);
// Prints:
// ITEM 3
// ITEM 4
// ITEM 1
// ITEM 2
```

Features.
---------

[](#features)

### Circular dependency detection.

[](#circular-dependency-detection)

Example:

```
use mdagostino\DependencyResolver\DependencyResolver;

$resolver = new DependencyResolver();
$resolver
  ->component('A')->requires('B')
  ->component('B')->requires('A');

$ordered = $resolver->resolveDependencies();

// Trow Exception: "Circular dependency detected"
```

### Check that all the components have been defined.

[](#check-that-all-the-components-have-been-defined)

Example:

```
use mdagostino\DependencyResolver\DependencyResolver;

$resolver = new DependencyResolver();
$resolver
  ->component('A')->requires('B', 'C')
  ->component('B');

  $ordered = $resolver->resolveDependencies();
  // Trow Exception: "There is a component not defined: C"
```
