Provider
========

[](#provider)

Common interfaces `ProviderInterface` and `ConsumerInterface` for inverting control of configuration. This allows a *consumer* to pass control to a *provider* so that the *provider* can configure the *consumer*.

The *consumer* must implement a `register()` method and the provider must implement a `provides()` method. An instance of *provider* is passed to `register()`, and `register()` in turn calls `provides()`, passing an instance of itself. This then allows the *provider* to call methods on the *consumer* and configure as needed.

In practice, this might look like:

```
use MattFerris\Provider\ConsumerInterface;
use MattFerris\Provider\ProviderInterface;

// service container which contains service definitions
class ServiceContainer implements ConsumerInterface
{
    public function register(ProviderInterface $provider)
    {
        $provider->provides($this);
        return $this;
    }

    ...
}

class DatabaseProvider implements ProviderInterface
{
    public function provides(ConsumerInterface $consumer)
    {
        $consumer->set('DatabaseService', $databaseServiceDefinition);
    }
}

$container = new ServiceContainer();
$container->register(new DatabaseProvider());
$db = $container->get('DatabaseService');
$db->query(...);
```

*Note*: `ProviderInterface` doesn't type-hint what kind of *consumer* it expects. This is on purpose, as *providers* implementing the interface can then validate the *consumer* based on what type they want. If a *consumer* isn't of they correct type, *providers* can throw an `InvalidConsumerException`.

Taking this example further, if an application contains multiple packages that each provide services, packages can configure their services automatically by implementing their own *providers*.

```
$container = new ServiceContainer();
$container
    ->register(new DatabasePackage\ServiceProvider())
    ->register(new Authentication\ServiceProvider())
    ->register(new EventDispatcher\ServiceProvider());
```
