Detailed Description

The ISvcManager is the interface implemented by the Service Factory in the Application Manager to support management functions.

Clients use this interface to declare abstract service factories, and to create concrete instances of services.

Member Function Documentation

virtual StatusCode ISvcManager::addService	(	IService *	svc,
		int	prio = `DEFAULT_SVC_PRIORITY`
	)

pure virtual

Add a service to the "active" list of services of the factory.

Parameters

svc	Pointer to the service

Returns: StatusCode indicating success or failure.

virtual StatusCode ISvcManager::addService	(	const std::string &	typ,
		const std::string &	nam,
		int	prio
	)

inlinevirtual

Add a service to the "active" list of services of the factory.

Parameters

svc	Pointer to the service

Returns: StatusCode indicating success or failure.

Definition at line 49 of file ISvcManager.h.

   {
     return addService( Gaudi::Utils::TypeNameString( nam, typ ), prio );
   }

virtual StatusCode ISvcManager::addService	(	const Gaudi::Utils::TypeNameString &	nametype,
		int	prio = `DEFAULT_SVC_PRIORITY`
	)

pure virtual

Add a service to the "active" list of services of the factory.

Parameters

svc	Pointer to the service

Returns: StatusCode indicating success or failure.

virtual SmartIF<IService>& ISvcManager::createService ( const Gaudi::Utils::TypeNameString & nametype )

pure virtual

Creates and instance of a service type that has been declared beforehand and assigns it a name.

It returns a pointer to an IService.

Parameters

nametype name/type of the service to create

Returns: SmartIF& to the created service.

NOTE: as this returns a &, the underlying implementation must guarantee that once created, these SmartIF remain pinned in their location, thus constraining the underlying implementation (i.e. one cannot use something like std::vector<SmartIF<IService>>). If this interface had used value-semantics, and returned just plain SmartIF<IService> (i.e. WITHOUT the &) then the underlying implementation would have much more freedom)

virtual StatusCode ISvcManager::createService	(	const std::string &	svctype,
		const std::string &	svcname,
		IService *&	svc
	)

inlinevirtual

Creates and instance of a service type that has been declared beforehand and assigns it a name.

It returns a pointer to an IService.

Parameters

svctype	Service type name
svcname	Service name to be set
svc	Returned service pointer

Returns: StatusCode indicating success or failure.

Definition at line 124 of file ISvcManager.h.

   {
     SmartIF<IService> s = createService( svctype + "/" + svcname );
     svc                 = s.get();
     if ( svc ) {
       svc->addRef(); // Needed to maintain the correct reference counting.
       return StatusCode::SUCCESS;
     }
     return StatusCode::FAILURE;
   }
