PndGeoHandling¶

class PndGeoHandling : public FairTask¶

Class to access the naming information of the MVD.

To save memory not the full path of a volume is stored in each hit but an encrypted form of it (f.e. /1_1/34_2/101_1/). The first number is the volumeID coming from the GeoManager and the second number is the copy number. This class helps converting the encrypted ID into the path information and vice versa. It needs the information of the GeoManager. Therefore one has to ensure that either an initialized TGeoManager pointer is given in the constructor with the correct geometry or a filename with the correct geometry (“FAIRGeom”)

30.03.2010: To reduce the data size a shortId is introduced. The shortId is generated with the command CreateUniqueSensorId and the match between the path in the GeoManager and the shortId is stored in the ParameterDatabase. To use the shortID the constructor of the PndGeoHandling has to be called in the method SetParContainers of a Task!

Public Functions

PndGeoHandling()¶

default constructor. Has to be called in SetParContainers if the support of shortId is needed.

PndGeoHandling::Instance() has to be called the first time in the constructor of a task otherwise the Sensor names are not available from the database
