Informations about the package injectable-bundle
Injectable-Bundle
Description
Injectable-bundle
is responsible for injecting array of objects into your class.
By tagging you mark an service to be injected into your target service.
Example use JMSDiExtraBundle, but you can
easily configure it with services.yml
Target Service
/**
* @DI\Service("template_factory")
*/
class TemplateFactory
{
/**
* @param array|Template[] $providers
*/
private $providers;
/**
* @DI\InjectParams({
* "providers" = @DI\Inject("%empty_array%")
* })
*/
public function __construct(array $providers)
{
$this->providers = $providers;
}
public function createFor(string $type) : Template
{
foreach ($this->providers as $provider) {
if ($provider->isHandling($type)) {
return $provider;
}
}
throw new \Exception("Template for {$type} doesn't exists!");
}
}
interface Template
{
public function render() : string
public function isHandling(string $type) : bool;
}
Injected Services
/**
* @DI\Service()
* @DI\Tag(name="injectable", attributes={"to"="template_factory", "index"="0"})
*/
class NiceTemplate implements Template
{
public function render()
{
return "nice template";
}
public function isHandling(string $type) : bool
{
return $type === 'nice';
}
}
/**
* @DI\Service()
* @DI\Tag(name="injectable", attributes={"to"="template_factory", "index"="0"})
*/
class UglyTemplate implements Template
{
public function render()
{
return "ugly template";
}
public function isHandling(string $type) : bool
{
return $type === 'ugly';
}
}
Above service will be injected into TemplateFactory.
If there will be no services tagged as injectable for template_factory
, template factory
will use of empty array.
Understanding the annotations
@DI\Tag(name="injectable", attributes={"to"="template_factory", "index"="0"})
name="injectable"
- Marks serviceto be used
by InjectableBundle"to"="template_factory"
- Sets target service"index"="0"
- Sets target service constructor argument index
