bool operator && ( SmartDataObjectPtr & object_1, SmartDataObjectPtr & object_2 )

Helper to test Smart data objects efficiently This construct allows statements like: SmartEvtDataPtr<MCVertexVector> mcvertices (evt,"/MC/MCVertices"); SmartEvtDataPtr<MCParticleVector> mctracks (evt,"/MC/MCParticles"); if ( mctracks && mcvertices ) { ... } and tests the existence of BOTH objects in the data store. This is not done inline due to danger of code explosion. Parameters: object_1   Smart pointer to object 1 object_2   Smart pointer to second object Returns: Boolean indicating existence of both objects Definition at line 169 of file SmartDataObjectPtr.cpp.

bool operator|| ( SmartDataObjectPtr & object_1, SmartDataObjectPtr & object_2 )

Helper to test Smart data objects efficiently This construct allows statements like: SmartEvtDataPtr<MCVertexVector> mcvertices (evt,"/MC/MCVertices"); SmartEvtDataPtr<MCParticleVector> mctracks (evt,"/MC/MCParticles"); if ( mctracks || mcvertices ) { ... } and tests the existence of at least one objects in the data store. The second object will then NOT be loaded. It is assumed that the second choice is only an alternative usable in case the first object cannot be retrieved. This is not done inline due to danger of code explosion. Parameters: object_1   Smart pointer to object 1 object_2   Smart pointer to second object Returns: Boolean indicating existence of both objects Definition at line 194 of file SmartDataObjectPtr.cpp.
