Dear pandaRooters,

I am looking for a way to figure out if a GeoManager is existing in a root session or not without crashing the program.

Unfortunately I have not found anything up to now, so I wonder if one of you can help me?

Looking forward for a positive reply,

Tobias

Hallo Tobias,
There is two ways to do this:

1. if you know the name of the TGeoManager object, you can use:

gROOT->FindObjectAny("ObjectName")

this will return a pointer to TGeo if it exist or a zero if not.
in case of PandaRoot it is always created with the default name "CBMGeom".

2. In case you do not no the name, you can call:

gROOT->GetListOfGeometries()

which will return you a TSeqCollection of existing geometries (TGeoManager objects) which you can check if it is empty or has some entries which will be the existing geometries.

regards

Mohammad
