## 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
| ) |  |
| inline 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.

Definition at line 48 of file ISvcManager.h.

48 {
49 return addService(Gaudi::Utils::TypeNameString(nam,typ), prio);
50 }
ISvcManager::addService
virtual StatusCode addService(IService *svc, int prio=DEFAULT_SVC_PRIORITY)=0
Add a service to the "active" list of services of the factory.
Gaudi::Utils::TypeNameString
Helper class to parse a string of format "type/name".
Definition: TypeNameString.h:12

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
| ) |  |
| inline 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

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

Returns
  StatusCode indicating success or failure.

Definition at line 123 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;

Definition: SmartIF.h:76
ISvcManager::createService
virtual SmartIF< IService > & createService(const Gaudi::Utils::TypeNameString &nametype)=0
Creates and instance of a service type that has been declared beforehand and assigns it a name...
