operator&&()

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 120 of file SmartDataObjectPtr.cpp.

                                                                              {
  return object_1.accessData() && object_2.accessData();
}

operator||()

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
