const mixinafIoc::Registry
afIoc::Registry
(Service) - The registry of IoC services; this is the main IoC interface.
- autobuild
abstract Obj autobuild(Type type, Obj?[]? ctorArgs := null, [Field:Obj?]? fieldVals := null)
Autobuilds an instance of the given type, resolving all dependencies:
- create instance via ctor marked with
@Inject
or the ctor with the most parameters - inject dependencies into fields (of all visibilities) marked with
@Inject
- call any methods annotated with
@PostInjection
ctorArgs
(if provided) will be passed as arguments to the first parameters in the autobuild ctor. Handy when you wish the ctor to take a mixture of plain objects and services. e.g. for a fwt::Command:registry.autobuild(MySaveCommand#, [entityToSave]) ... class MySaveCommand { @Inject private EntityDao entityDao private Entity entity new make(Entity entity, OtherService service, |This| injectInto) { injectInto(this) // ioc to inject all fields service.doSomething // this service is only used here, so doesn't need to be a field entityDao.save(entity) // use the field service and passed in entity } }
Note: the passed in parameters must be first in the ctor parameter list.
fieldVals
set (and potentially overwrite) the value of any const fields set by an it-block function.- create instance via ctor marked with
- callMethod
abstract Obj? callMethod(Method method, Obj? instance, Obj?[]? providedMethodArgs := null)
Calls the method, dependency injecting the parameters.
instance
can benull
if calling a static method.The optional
providedMethodArgs
are used as method arguments. Any args not provided are dependency injected; unless they have a default argument, in which case nothing is passed in and the default is used.@since 1.5.0
- createProxy
abstract Obj createProxy(Type mixinType, Type? implType := null, Obj?[]? ctorArgs := null, [Field:Obj?]? fieldVals := null)
A companion method to
autobuild
. Creates an instance of the given mixin, which creates the real instance whenever a mixin method is invoked.If
implType
is null then it is assumed to have the same name as the mixin, plus aImpl
suffix.@since 1.5.0
- dependencyByType
abstract Obj? dependencyByType(Type dependencyType, Bool checked := true)
Locates a dependency of the given type.
- injectIntoFields
abstract Obj injectIntoFields(Obj instance)
Injects services and dependencies into fields (of all visibilities) marked with
@Inject
.Returns the object passed in for method chaining.
Note: use
autobuild()
if your fields are const / not-nullable.- serviceById
abstract Obj? serviceById(Str serviceId, Bool checked := true)
Obtains a service via its unique service id.
- serviceDefinitions
abstract Str:ServiceDefinition serviceDefinitions()
Returns a map of all service definitions (keyed by service id) held by this IoC. Useful for the inquisitive.
@since 2.0.0
- shutdown
abstract This shutdown()
Shuts down the Registry. Notifies all listeners that the registry has shutdown. Further method invocations on the Registry are no longer allowed, and the Registry instance should be discarded.
See RegistryShutdown service for details on how to add shutdown listeners.
- startup
abstract This startup()
Invoke to execute all listeners in (or contributions to) the RegistryStartup service.
