Member Function Documentation

create()

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

virtual

Create the AWESOME detector geometry in the world volume.

Parameters

content	Gearbox path to the detector geometry.
topVolume	Geant4 world volume.

Implements CreatorBase.

  /* Let's get the stepsize parameter with a default value of 5 µm. */
  double stepSize = content.getLength("stepSize", 5 * Unit::um);
  /* Now get the array. Notice that the default framework unit is cm,
   * so the values will be automatically converted. */

  }
}

createFromDB()

void createFromDB ( const std::string &  name, G4LogicalVolume &  topVolume, GeometryTypes  type  )

virtualinherited

Function to create the geometry from the Database.

Parameters

name	name of the component in the database, could be used to disambiguate multiple components created with the same creator
topVolume	Top volume in which the geometry has to be placed
type	Type of geometry to be build

Reimplemented in MyDBCreator, and GeoMagneticField.

Definition at line 17 of file CreatorBase.cc.

    {
      //Do nothing but raise exception that we don't do anything
      throw DBNotImplemented();
    }

createPayloads()

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

virtualinherited

Function to create the geometry database.

This function should be implemented to convert Gearbox parameters to one ore more database payloads

Parameters

content	GearDir pointing to the parameters which should be used for construction
iov	interval of validity to use when generating payloads

Reimplemented in MyDBCreator, and GeoMagneticField.
