Member Function Documentation

create()

virtual void create ( const GearDir &  content, G4LogicalVolume &  topVolume, geometry::GeometryTypes  type  )

inlineoverridevirtual

Creates the Geant4 objects for the structure geometry from Gearbox.

This is the 'old' way of building the geometry from Gearbox (xml files). Expected to be deprecated in the future.

Parameters

content	A reference to the content part of the parameter description, which should to be used to create the ROOT objects.
topVolume	Geant4 logical top volume.
type	Geometry type.

Implements CreatorBase.

Definition at line 55 of file GeoSTRCreator.h.

      {
        STRGeometryPar config = createConfiguration(content);
        createGeometry(config, topVolume, type);
      }

createConfiguration()

STRGeometryPar createConfiguration ( const GearDir &  param )

private

Create a parameter object from the Gearbox XML parameters.

If more than one object is created these could be assigned to members or you could return a tuple.

Definition at line 148 of file GeoSTRCreator.cc.

    {
      STRGeometryPar strGeometryPar;
 
      // Get STR geometry parameters from Gearbox (no calculations here)
      readShield(param, strGeometryPar, "FWD_Shield");
      readShield(param, strGeometryPar, "BWD_Shield");
      readPole(param, strGeometryPar, "PolePieceL");
      readPole(param, strGeometryPar, "PolePieceR");
 
 
      return strGeometryPar;
    };

createGeometry()

void createGeometry ( const STRGeometryPar &  parameters, G4LogicalVolume &  topVolume, geometry::GeometryTypes  type  )

private

Create the geometry from a parameter object.

If more than one object is needed these could instead be taken from member variables or the number of parameters could be increased.

Definition at line 62 of file GeoSTRCreator.cc.

createPayloads()

virtual void createPayloads ( const GearDir &  content, const IntervalOfValidity &  iov  )

inlineoverridevirtual

Create the configuration objects and save them in the Database.

If more than one object is needed adjust accordingly

Reimplemented from CreatorBase.
