Member Function Documentation

◆ createGeometry() [1/2]

void createGeometry	(	const GearDir &	params,
		GeometryTypes	type = `FullGeometry`
	)

Create Geometry.

This function will create the geometry representation. First the Materials will be created, than the top volume will be defined and all components of the detector will be built by calling the corresponding creator

Parameters

params	GearDir pointing to the top element of the geometry parameters
type	Type of the geometry to be built

Definition at line 219 of file GeometryManager.cc.

     {
       GeoConfiguration config = createGeometryConfig(detectorDir, IntervalOfValidity());
       createGeometry(config, type, false);
     }

◆ createGeometry() [2/2]

void createGeometry	(	const GeoConfiguration &	params,
		GeometryTypes	type = `FullGeometry`,
		bool	useDB = `true`
	)

Create Geometry.

This function will create the geometry representation from an existing configuration object. First the Materials will be created, than the top volume will be defined and all components of the detector will be built by calling the corresponding creator

Parameters

params	geometry configuration object
type	Type of the geometry to be built
useDB	whether the creators should be using the Database or Gearbox

Definition at line 225 of file GeometryManager.cc.

◆ createGeometryConfig()

GeoConfiguration createGeometryConfig	(	const GearDir &	detectorDir,
		const IntervalOfValidity &	iov
	)

Create Geometry configuration object.

This function will convert a Gearbox representation of the geometry to an object containing all necessary parameters

Parameters

detectorDir	GearDir pointing to the top element of the geometry parameters
iov	Interval of validity for the created object

Definition at line 122 of file GeometryManager.cc.

◆ createTGeoRepresentation()

void createTGeoRepresentation ( )

Create a TGeo representation of the native geometry description.

This method will convert the existing Geometry to a ROOT TGeo representation which can be accessed using the global gGeoManager provided by ROOT.

Definition at line 348 of file GeometryManager.cc.

◆ getTopVolume()

G4VPhysicalVolume* getTopVolume ( )

inline

Return a pointer to the top volume.

Returns 0 if no geometry has been created so far

Definition at line 56 of file GeometryManager.h.

◆ newVisAttributes()

G4VisAttributes * newVisAttributes ( )

Create an anonymous G4VisAttributes for an existing G4LogicalVolume.

Returns: Pointer to the new G4VisAttributes object

Definition at line 371 of file GeometryManager.cc.

◆ setAdditionalComponents()

void setAdditionalComponents ( const std::vector< std::string > & components )

inline

Set the names of addtional components to be added to the default set.

This member allows to set a list of component names. When creating the the geometry, components matching names in the list will be added if they are not disabled by default. If a list of components is already provided this list is ignored.

Parameters

components List of detector components to be added in addition

Definition at line 125 of file GeometryManager.h.

◆ setAssignRegions()

void setAssignRegions ( bool assignRegions )

inline

Choose whether a region should be assigned to each creator.

If set to true, all volumes created by each creator are assigned a region with the name of the creator

Definition at line 143 of file GeometryManager.h.

◆ setDetectorComponents()

void setDetectorComponents ( const std::vector< std::string > & components )

inline

Set the names of the components to create.

This member allows to set a list of component names. When creating the the geometry, only components matching names in the list will be created. All other components found in the parameters will be ignored

Parameters

components List of detector components to be created

Definition at line 98 of file GeometryManager.h.

◆ setExcludedComponents()

void setExcludedComponents ( const std::vector< std::string > & components )

inline

Set the names of the components to exclude from creation.

This member allows to set a list of component names. When creating the the geometry, components matching names in the list will be ignored

Parameters

components List of detector components to be excluded
