How to Inject Instances into the Container
5+
------------------------------------------
6+
7+
When using the container in your application, you sometimes need to inject an
8+
instance instead of configuring the container to create a new instance.
9+
10+
For instance, if you're using the:doc:`HttpKernel</components/http_kernel/introduction>`
11+
component with the DependencyInjection component, then the ``kernel``
12+
service is injected into the container from within the ``Kernel`` class::
13+
14+
// ...
15+
abstract class Kernel implements KernelInterface, TerminableInterface
16+
{
17+
// ...
18+
protected function initializeContainer()
19+
{
20+
// ...
21+
$this->container->set('kernel', $this);
22+
23+
// ...
24+
}
25+
}
26+
27+
The ``kernel`` service is called a synthetic service. This service has to be
28+
configured in the container, so the container knows the service does exist
29+
during compilation (otherwise, services depending on this ``kernel`` service
30+
will get a "service does not exists" error).
31+
32+
In order to do so, you have to use
33+
:method:`Definition::setSynthetic() <Symfony\\Component\\DependencyInjection\\Definition::setSynthetic>`::
34+
35+
use Symfony\Component\DependencyInjectino\Definition;
36+
37+
// synthetic services don't specify a class
38+
$kernelDefinition = new Definition();
39+
$kernelDefinition->setSynthetic(true);
40+
41+
$container->setDefinition('your_service', $kernelDefinition);
42+
43+
Now, you can inject the instance in the container using
44+
:method:`Container::set() <Symfony\\Component\\DependencyInjection\\Container::set>`::
45+
46+
$yourService = new YourObject();
47+
$container->set('your_service', $yourService);
48+
49+
``$container->get('your_service')`` will now return the same instance as
50+
``$yourService``.
