Any VuFind plugin accessed through a standard plugin interface can implement certain “-Aware” interfaces in order to be automatically injected with dependencies. This is a convenient way to gain access to other elements of the VuFind system.

Here are the relevant interfaces:

• \VuFind\Db\Table\DbTableAwareInterface - Get access to the VuFind\DbTablePluginManager service
• \VuFind\I18n\Translator\TranslatorAwareInterface - Get access to the VuFind\Translator service
• \VuFindHttp\HttpServiceAwareInterface - Get access to the VuFind\Http service
• \Zend\Log\LoggerAwareInterface - Get access to the VuFind\Logger service
• \Zend\ServiceManager\ServiceLocatorAwareInterface - Get access to the plugin manager that constructed the current object
• \ZfcRbac\Service\AuthorizationServiceAwareInterface - Get access to the authorization service (for permission checks)

You can also implement a setPluginManager() method as an alternative to implementing the \Zend\ServiceManager\ServiceLocatorAwareInterface; the result is the same.

Starting with VuFind 2.4, Traits are provided which can be used in addition to interfaces to automatically implement interface-specific methods (and in some case, useful related utility methods). These Traits can help to reduce redundancy in your code:

• \VuFind\Db\Table\DbTableAwareTrait
• \VuFind\I18n\Translator\TranslatorAwareTrait
• \VuFindHttp\HttpServiceAwareTrait
• \VuFind\Log\LoggerAwareTrait
• \Zend\ServiceManager\ServiceLocatorAwareTrait
• \ZfcRbac\Service\AuthorizationServiceAwareInterface
