Detailed Description

Load a GDML file into memory.

The pointer treatment gives three options:

• ignore leaves names as they are imported by Geant4's GDML reader, which strips them from material/region names but leaves solid/logical/physical pointers in place.
• truncate lets the Geant4 GDML remove the pointers, which cuts everything after 0x including suffixes like _refl added during volume construction.
• remove uses a regular expression to remove pointers from volume names.

The detectors option reads auxiliary tags in the structure that have auxtype=SensDet and returns a multimap of strings to volume pointers.

PointerTreatment

enum class celeritas::GeantGdmlLoader::PointerTreatment

strong

How to handle pointers in volume names.

Enumerator
ignore	Pointers will remain in the volume name.
truncate	All text after '0x' is removed.
remove	Only pointers are carefully removed.

Member Function Documentation

operator()()

auto celeritas::GeantGdmlLoader::operator() ( std::string const &  filename ) const

inline

Load a gdml input file, creating a pointer owned by Geant4.

Geant4's constructors for physical/logical volumes register this pointers in the "volume stores" which can be cleared with celeritas::reset_geant_geometry .

Note that material and element names (at least as of Geant4@11.0) are always stripped: only volumes and solids keep their extension.
