Overview of the Dependency Injection Container and Services. Overview of container, injection, and services The Services and Dependency Injection Container concepts have been adopted by Drupal from the Symfony framework. A "service" (such as accessing the database, sending email, or translating user interface text) is defined (given a name and an interface or at least a class that defines the methods that may be called), and a default class is designated to provide the service. These two steps

Service tags overview Some services have tags, which are defined in the service definition. Tags are used to define a group of related services, or to specify some aspect of how the service behaves. Typically, if you tag a service, your service class must also implement a corresponding interface. Some common examples: access_check: Indicates a route access checking service; see the Menu and routing system topic for more information. cache.bin: Indicates a cache bin service; see the Cache topi
