Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

createServiceCreator

public ObjectCreator createServiceCreator(ServiceBuilderResources resources)

Description copied from interface: ServiceDef

Returns an ObjectCreator that can create the core service implementation.

Specified by:

createServiceCreator in interface ServiceDef

Parameters:

resources - used to resolve dependencies of the service, or access its configuration

Returns:

an object that can (later) be used to instantiate the service itself

getServiceId

public java.lang.String getServiceId()

Description copied from interface: ServiceDef

Returns the service id, derived from the method name or the unqualified service interface name. Service ids must be unique among all services in all modules. Service ids are used in a heavy handed way to support ultimate disambiguation, but their primary purpose is to support service contribution methods.

Specified by:

getServiceId in interface ServiceDef

getServiceInterface

public java.lang.Class getServiceInterface()

Description copied from interface: ServiceDef

Returns the service interface associated with this service. This is the interface exposed to the outside world, as well as the one used to build proxies. In cases where the service is not defined in terms of an interface, this will return the actual implementation class of the service. Services without a true service interface are not proxied, which has a number of ramifications (such as losing lazy instantiation capabilities and other more interesting lifecycles).

Specified by:

getServiceInterface in interface ServiceDef

getServiceScope

public java.lang.String getServiceScope()

Description copied from interface: ServiceDef

Returns the lifecycle defined for the service. This is indicated by adding a Scope annotation to the service builder method for the service.

Services that are not proxied will ignore their scope; such services are always treated as singletons.

Specified by:

getServiceScope in interface ServiceDef

ServiceLifecycle, ServiceLifecycleSource

isEagerLoad

public boolean isEagerLoad()

Description copied from interface: ServiceDef

Returns true if the service should be eagerly loaded at Registry startup.

Specified by:

isEagerLoad in interface ServiceDef

See Also:

EagerLoad

getMarkers

public java.util.Set<java.lang.Class> getMarkers()

Description copied from interface: ServiceDef

Returns an optional set of marker annotations. Marker annotations are used to disambiguate services; the combination of a marker annotation and a service type is expected to be unique. The annotation is placed on the field or method/constructor parameter and the service is located by combining the marker with service type (the parameter or field type).

Specified by:

getMarkers in interface ServiceDef

Returns:

the marker annotations for the service (possibly empty), including any default marker annotations from the containing module.

isPreventDecoration

public boolean isPreventDecoration()

Description copied from interface: ServiceDef2

Returns true if the service should not be decorated. Most services allow decoration, unless the PreventServiceDecoration annotation is present.

Specified by:

isPreventDecoration in interface ServiceDef2

getImplementationClass

public java.lang.Class getImplementationClass()

Description copied from interface: InternalServiceDef

Returns the service implementation class.

Specified by:

getImplementationClass in interface InternalServiceDef

Returns:

implementations class or null
