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
svcPointer 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
svcPointer to the service
Returns
StatusCode indicating success or failure.

Definition at line 49 of file ISvcManager.h.

50  {
51  return addService( Gaudi::Utils::TypeNameString( nam, typ ), prio );
52  }
virtual StatusCode addService(IService *svc, int prio=DEFAULT_SVC_PRIORITY)=0
Add a service to the "active" list of services of the factory.
Helper class to parse a string of format "type/name".
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
svcPointer 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
nametypename/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
svctypeService type name
svcnameService name to be set
svcReturned service pointer
Returns
StatusCode indicating success or failure.

Definition at line 124 of file ISvcManager.h.

125  {
126  SmartIF<IService> s = createService( svctype + "/" + svcname );
127  svc = s.get();
128  if ( svc ) {
129  svc->addRef(); // Needed to maintain the correct reference counting.
130  return StatusCode::SUCCESS;
131  }
132  return StatusCode::FAILURE;
133  }
TYPE * get() const
Get interface pointer.
