template<class TYPE >

bool GaudiCommon< PBASE >::exist ( IDataProviderSvc *  svc, const std::string &  location, const bool  useRootInTES = true  ) const

inline

Check the existence of a data object or container in the Gaudi Transient Event Store.

bool a1 = exist<DataObject>( evtSvc() , "/Event/MyObject" ) ;
bool a2 = exist<MyHits>    ( evtSvc() , "/Event/MyHits" ) ;

Attention

The method respects the setting of the job option RootInTES by prepending the value of this to the data location that is passed. The default setting for RootInTES is "" so has no effect. This behavior can be suppressed by passing the argument useRootInTES = false

Parameters

svc	Pointer to data provider service
location	Address in Gaudi Transient Store
useRootInTES	Flag to turn on(TRUE) off(FALSE) the use of the RootInTES location property

Returns

Boolean indicating status of the request

Return values

true	Data object or container exists and implements a proper interface
true	Failed to locate the data object or container

Definition at line 78 of file GaudiCommonImp.h.

Gaudi::Utils::GetData< TYPE >::return_type GaudiCommon< PBASE >::getOrCreate ( IDataProviderSvc *  svc, const std::string &  location, const bool  useRootInTES = true  ) const

inline

Get the existing data object from Gaudi Event Transient store.

Alternatively, create new object and register it in TES and return if object does not exist.

MyHits* hits = getOrCreate<MyHits,MyHits>( evtSvc() , "/Event/MyHits" ) ;

Attention

The method respects the setting of the job option RootInTES by prepending the value of this to the data location that is passed. The default setting for RootInTES is "" so has no effect. This behavior can be suppressed by passing the argument useRootInTES = false

Exceptions

GaudiException	for Invalid Data Provider Service
GaudiException	for invalid/unavailable data

Parameters

svc	Pointer to data provider service
location	Location in Gaudi Transient Event Store
useRootInTES	Flag to turn on(TRUE) off(FALSE) the use of the RootInTES location property

Returns

A valid pointer to the data object

TOOL * GaudiCommon< PBASE >::tool ( const std::string &  type, const IInterface *  parent = 0, bool  create = true  ) const

inline

A useful method for the easy location of tools.

IMyTool* myTool = tool<IMyTool>( "PublicToolType" );

Attention

The tools located with this method will be released automatically
