## Member Function Documentation

virtual void IUpdateManagerSvc::acquireLock | ( | ) | `[pure virtual]`

Force the update manager service to wait before entering the newEvent loop.

virtual IDataProviderSvc* IUpdateManagerSvc::dataProvider | ( | ) | const`[pure virtual]`

Give access to the data provider.

IUpdateManagerSvc::DeclareInterfaceID | ( | IUpdateManagerSvc | ,
|  | 2 | ,
|  | 0 |
| ) |  |

InterfaceID.

virtual IDetDataSvc* IUpdateManagerSvc::detDataSvc | ( | ) | const`[pure virtual]`

Give access to the detector data service interface (usualy of the data provider itself).

virtual void IUpdateManagerSvc::dump | ( | ) | `[pure virtual]`

Debug method: it dumps the dependency network through the message service (not very readable, for experts only).

virtual bool IUpdateManagerSvc::getValidity | ( | const std::string | path,
|  | Gaudi::Time & | since,
|  | Gaudi::Time & | until,
|  | bool | path_to_db = `false`
| ) |  | `[pure virtual]`

Retrieve the interval of validity (in the UpdateManagerSvc) of the given item.

Returns:
  false if the item was not found.

virtual void IUpdateManagerSvc::i_invalidate | ( | void * | instance ) | `[protected, pure virtual]`

virtual void IUpdateManagerSvc::i_registerCondition | ( | const std::string & | condition,
|  | BaseObjectMemberFunction * | mf,
|  | BasePtrSetter * | ptr_dest = `NULL`
| ) |  | `[protected, pure virtual]`

virtual void IUpdateManagerSvc::i_registerCondition | ( | void * | obj,
|  | BaseObjectMemberFunction * | mf
| ) |  | `[protected, pure virtual]`

virtual void IUpdateManagerSvc::i_unregister | ( | void * | instance ) | `[protected, pure virtual]`

virtual StatusCode IUpdateManagerSvc::i_update | ( | void * | instance ) | `[protected, pure virtual]`

template<class CallerClass >

void IUpdateManagerSvc::invalidate | ( | CallerClass * | instance ) | `[inline]`

Invalidate the given object in the dependency network.

It means that all the objects depending on that one will be updated before the next event.

Definition at line 233 of file IUpdateManagerSvc.h.

    {i_invalidate(dynamic_cast<void*>(instance));}

virtual StatusCode IUpdateManagerSvc::newEvent | ( | ) | `[pure virtual]`

Start an update loop using the event time given by the detector data service.

virtual StatusCode IUpdateManagerSvc::newEvent | ( | const Gaudi::Time & | ) | `[pure virtual]`

Start an update loop using the give event time.

NOTE: the given event time is only used to check if updates are needed, the real update is done using the detector data service event time. (may change in future)

virtual void IUpdateManagerSvc::purge | ( | ) | `[pure virtual]`

Remove all the items referring to objects present in the transient store.

This is needed when the Detector Transient Store is purged, otherwise we will keep pointers to not existing objects.

template<class CallerClass , class ObjectClass >

void IUpdateManagerSvc::registerCondition | ( | CallerClass * | instance,
|  | ObjectClass * | obj,
|  | typename ObjectMemberFunction< CallerClass >::MemberFunctionType | mf = `NULL`
| ) |  | `[inline]`

Like the first version of registerCondition, but instead declaring the dependency on a condition of the service privider, it uses an already registered object.

It means that a generic object can depend on another generic object that depends on a ValidDataObject. The dependency network is kept consistent by the UpdateManagerSvc.

                                                                                                           {
            i_registerCondition(dynamic_cast<void*>(obj), new ObjectMemberFunction<CallerClass>(instance,mf));
      }

template<class CallerClass >

void IUpdateManagerSvc::registerCondition | ( | CallerClass * | instance,
|  | const std::string & | condition = `""`,
|  | typename ObjectMemberFunction< CallerClass >::MemberFunctionType | mf = `NULL`
| ) |  | `[inline]`

Register an object (algorithm instance) to the service.

The object should provide a method to be called in case of an update of the needed condition. An object can register multiple conditions using the same method: it will be called if at least one of the specified conditions is updated, but only when all of them are up to date.

Returns:
  StatusCode::SUCCESS if the registration went right.

                                                                                                           {
        i_registerCondition(condition, new ObjectMemberFunction<CallerClass>(instance,mf));
      }

template<class CallerClass , class CondType >

void IUpdateManagerSvc::registerCondition | ( | CallerClass * | instance,
|  | const std::string & | condition,
|  | typename ObjectMemberFunction< CallerClass >::MemberFunctionType | mf,
|  | CondType *& | condPtrDest
| ) |  | `[inline]`

Definition at line 199 of file IUpdateManagerSvc.h.

                                                           {
        i_registerCondition(condition, new ObjectMemberFunction<CallerClass>(instance,mf),
                            new PtrSetter<CondType>(condPtrDest));
      }

template<class CallerClass >

void IUpdateManagerSvc::registerCondition | ( | CallerClass * | instance,
|  | const char * | condition,
|  | typename ObjectMemberFunction< CallerClass >::MemberFunctionType | mf = `NULL`
| ) |  | `[inline]`

See above. Needed to avoid conflicts with the next one.

Definition at line 208 of file IUpdateManagerSvc.h.

                                                                                                           {
        i_registerCondition(std::string(condition), new ObjectMemberFunction<CallerClass>(instance,mf));
      }

virtual void IUpdateManagerSvc::releaseLock | ( | ) | `[pure virtual]`

Let the update manager service enter the newEvent loop.

virtual void IUpdateManagerSvc::setValidity | ( | const std::string | path,
|  | const Gaudi::Time & | since,
|  | const Gaudi::Time & | until,
|  | bool | path_to_db = `false`
| ) |  | `[pure virtual]`

Change the interval of validity of the given item to the specified values, updating parents if needed.

The change can only restrict the current IOV, If you want to expand the validity you should act on the transient data store and the change will be reflected at the next update.

template<class CallerClass >

void IUpdateManagerSvc::unregister | ( | CallerClass * | instance ) | `[inline]`

Generic objects can be unregistered from the UpdateManagerSvc.

The dependency network is always consistent, but internal IOVs are not modified.

Warning:
  {Removing a node which other nodes depends on can create problems if the methods of this other nodes are called.}

Definition at line 226 of file IUpdateManagerSvc.h.

                                                    {
        i_unregister(dynamic_cast<void*>(instance));
      }

template<class CallerClass >

StatusCode IUpdateManagerSvc::update | ( | CallerClass * | instance ) | `[inline]`

Update the given instance.

This method should be called by the object after registration to ensure that the needed operations is done immediately and not before the next event.

Definition at line 256 of file IUpdateManagerSvc.h.

                                                     {
        return i_update(dynamic_cast<void*>(instance));
      }
