Annotation Type Scope

@Target(value={TYPE,METHOD})
@Retention(value=RUNTIME)
@Documented
@UseWith(value={SERVICE,MODULE})
public @interface Scope

An optional annotation that may be placed on a service building method of a module, or on the implementation class (when using service binding). The annotation overrides the default scope for services (the default being a global singleton that is instantiated on demand) for an alternate lifecycle. Alternate lifecycles are typically used to bind a service implementation to a single thread or request. Modules may define new scopes. Each scope should have a corresponding ServiceLifecycle implementation. The linkage from scope name to service lifecycle occurs via a contribution to the ServiceLifecycleSource service configuration.

The annotation may also be placed directly on a service implementation class, when using service binding (via the ServiceBinder).
