public abstract class AuthenticatedInjectedService
extends InitialisedInjectedService

This class is similar to AbstractAuthenticatedService. Like InitialisedInjectedService this injected service will not be of much use before initialised by the platform. For instance, there will be no session factory, so no creation and no verification of session tokens can take place. Check with InitialisedInjectedService.isInitialised() whether the injected service is usable. Methods that usually wait for this service to be started, will not block but throw an exception before the initialisation. This is similar to their behaviour after the service has been shut down.

Constructor Detail

AuthenticatedInjectedService

public AuthenticatedInjectedService(java.util.logging.Logger logger)

Creates an injected service that can be initialised by the platform and provides a session factory. It assumes that there are no other services required.

Parameters:

logger - The logger which to use for this service. This will only be used until initialisation by the platform. Afterwards the logger of the AbstractADEPT2Service will be used.

AuthenticatedInjectedService

public AuthenticatedInjectedService(java.util.logging.Logger logger,
                                    java.lang.String[] startupRequiredServices,
                                    java.lang.String[] runtimeRequiredServices,
                                    java.lang.Class<?> cls)

Creates an injected service that can be initialised by the platform and provides a session factory. It uses the designated services from the platform.

Parameters:

logger - The logger which to use for this service. This will only be used until initialisation by the platform. Afterwards the logger of the AbstractADEPT2Service will be used.

startupRequiredServices - The service type names of services required at startup time (in InitialisedInjectedService.init(URI[], URI[]) and InitialisedInjectedService.start()).

runtimeRequiredServices - The service type names of services required at runtime (after startup time).

cls - The class which to use for the logger provided by AbstractADEPT2Service, this is usually the interface of the service.

Method Detail

initPlatform

public void initPlatform(Configuration conf,
                         Registry registry)
                  throws AbortServiceException

Creates a wrapped AbstractAuthenticatedService.

Overrides:

initPlatform in class InitialisedInjectedService

Parameters:

conf - The configuration provided by the platform.

registry - The registry allowing to access the platform.

Throws:

AbortServiceException - If there are problems initialising this service, an AbortServiceException will be thrown.

getServiceInstanceName

public SerialisableTriple<java.lang.String,java.lang.String,java.lang.String> getServiceInstanceName()

Description copied from interface: ADEPT2Service

Gets the (optional) cluster name, the unique node name and the hierarchical instance name of this service.

Specified by:

getServiceInstanceName in interface ADEPT2Service

Overrides:

getServiceInstanceName in class InjectedADEPT2Service

Returns:

The (optional) cluster name, the unique node name and the hierarchical instance name of this service.
