README
This bundle allows adding calls in container to other services, as though they were declared there. Allows some decoupling - the hottest thing in OOP.
Symfony 3.4 and 4.0 Note
As of version 3.4 and 4.0 of Symfony, Dependency Injector is able to find all tagged services on its own:
http://symfony.com/doc/current/service_container/tags.html#reference-tagged-services
This Bundle still works, and can be useful in some cases, e.g. when it's impossible to overwrite or modify declaration of the "parent" class.
Installation
composer require ojezu/add-call-to-remote-service-bundle
Usage
Register this bundle in app/appKernel.php:
class AppKernel extends Kernel { public function registerBundles() { $bundles = array( new OJezu\ConfigurableDiscriminationBundle\AddCallToRemoteServiceBundle(), // app bundles new Acme\TestBundle\ParentBundle(), new Acme\TestBundle\ChildABundle(), new Acme\TestBundle\ChildBBundle(), ); return $bundles; } }
Now, instead of:
services: acme.root_service: class: Acme\Services\RootService calls: - ['registerChildService', ['Foo', '@acme.children.foo']] - ['registerChildService', ['Bar', '@acme.children.bar', {'foo': 'bar'}]] acme.children.foo: class: Acme\Services\Children\FooService acme.children.bar: class: Acme\Services\Children\BarService
You can do this!
services: acme.root_service: class: Acme\Services\RootService
services: acme.children.foo: class: Acme\Services\Children\FooService public: false tags: - name: 'ojezu.add_call_to_remote_service' remote_service: '@acme.root_service' method: 'registerChildService' argument.0: 'Foo' argument.1: '@' argument.2.foo: 'bar'
services: acme.children.bar: class: Acme\Services\Children\BarService public: false tags: - name: 'ojezu.add_call_to_remote_service' remote_service: '@acme.root_service' method: 'registerChildService' argument.0: 'Bar' argument.1: '@'
'@'
will resolve to acme.children.foo
and acme.children.bar
respectively!
Questions
Why argument.0
, argument.1
, argument.2.foo
and not an array?
Symfony/DependencyInjector does not support that. All tag attributes must be scalars, because of XML format supported and used internally by DependencyInjector.
Will this load my services when they are unneeded?
No! This bundle modifies only definitions of services in container, it does not need to (and does not) load referenced services.
