Function Documentation

foreach_detector()

template<class F >

void celeritas::foreach_detector ( GeantGdmlLoader::MapDetectors const &  dets, F &&  apply_to_range  )

inline

Apply a function to each sensitive detector name with a range of volumes.

The input function should have a signature

void(*)(MDCIter start, MDCIter stop) 

where

using MDCIter = MapDetectors::const_iterator 

.

In C++23 this is equivalent to:

#include <ranges>
namespace rv = std::views;
 
template<class F>
void foreach_detector(MapDetectors const& dets, F&& f)
{
    for (auto chunk : dets | rv::chunk_by(
             [](auto const& a, auto const& b){ return a.first == b.first; }))
    {
        f(chunk.begin(), chunk.end());
    }
}

load_gdml()

G4VPhysicalVolume * celeritas::load_gdml ( std::string const &  filename )

inline

Load a Geant4 geometry, excising pointers.

This provides a good default for using GDML in Celeritas.

Returns

Geant4-owned world volume
