php - Accessing Files Relative to Bundle in Symfony2

Question

In a Symfony2 app's routing configuration, I can refer to a file like this:

somepage:
    prefix: someprefix
    resource: "@SomeBundle/Resources/config/config.yml"

Is there any way to access a file relative to the bundle within a controller or other PHP code? In particular, I'm trying to use a SymfonyComponentYamlParser object to parse a file, and I don't want to refer to that file absolutely. Essentially, I want to do this:

$parser = new Parser();
$config = $parser->parse( file_get_contents("@SomeBundle/Resources/config/config.yml") );

I've checked out the SymfonyComponentFinderFinder class, but I don't think that's what I'm looking for. Any ideas? Or maybe I'm completely overlooking a better way of doing this?

As a matter of fact, there is a service you could use for this, the kernel ($this->get('kernel')). It has a method called locateResource().

For example:

$kernel = $container->getService('kernel');
$path = $kernel->locateResource('@AdmeDemoBundle/path/to/file/Foo.txt');
