Descent Framework Dependency Injection Container

### The dependency builder

[](#the-dependency-builder)

This component serves a general dependency builder implementation implemented as `Descent\Services\DependencyBuilder`. The dependency builder orchestrates dependencies by constructing them without configuration. Optionally provided parameters and a list of enforced parameters are priorized in the building process.

##### Building an object from a interface factory

[](#building-an-object-from-a-interface-factory)

```
use Descent\Services\{
    DependencyBuilder,
    Entities\Factory
};

$builder = new DependencyBuilder();
$factory = new Factory(
    DateTimeInterface::class,
    function(string $time, string $zone = null) {
        return new DateTime(
            $time,
            new DateTimeZone($zone ?? 'europe/berlin')
        );
    }
);

$object = $builder->build($factory, ['time' => 'now']);
```

##### Building an object from a interface

[](#building-an-object-from-a-interface)

```
use Descent\Services\{
    DependencyBuilder
};

class Foo {

}

class Bar {
    protected $foo;

    public function __constrct(Foo $foo)
    {
        $this->foo = $foo;
    }
}

$builder = new DependencyBuilder();

$object = $builder->make(Bar::class);
```

### The dependency injection container

[](#the-dependency-injection-container)

This component serves a general dependency injection container implementation implemented as `Descent\Services\DependencyInjectionContainer`. The dependency injection container allows to register services as interface concrete assignments (service) as well as interface callback assignments (factories). The dependency injection container extends the dependency builder and alters the interface resolving of the dependency builder to seek for registered interfaces first.

##### Building objects from registered services

[](#building-objects-from-registered-services)

```
use Descent\Services\{
    DependencyInjectionContainer
};

class Foo {

}

class Bar {
    protected $foo;

    public function __constrct(Foo $foo)
    {
        $this->foo = $foo;
    }
}

$container = new DependencyInjectionContainer();

$container->bind(Foo::class)->singleton();
$container->bind(Bar::class);

$object = $container->make(Bar::class);
```

##### Building objects from registered factories

[](#building-objects-from-registered-factories)

```
use Descent\Services\{
    DependencyInjectionContainer
};

class Foo {

}

class Bar {
    protected $foo;
    protected $bar;

    public function __constrct(Foo $foo, Foo $bar)
    {
        $this->foo = $foo;
        $this->bar = $bar;
    }
}

$container = new DependencyInjectionContainer();

$container->bind(Foo::class)->singleton();
$container->factory(
    Bar::class,
    function(Foo $foo, Foo $bar = null) {
        return new Bar($foo, $bar ?? $foo);
    }
)->enforceParameters('bar');

$object = $container->make(Bar::class);
```
