Detailed Description

Create an ImportData object from a ROOT data file.

RootImporter loads particle, element, material, process, and volume information from a ROOT file that contains an ImportData object. Currently, said ROOT file is created by the RootExporter class. The imported data will be converted to the native unit system.

RootImporter , along with all Import[Class] type of classes, are the link between Geant4 and Celeritas. Every Celeritas' host/device class that relies on imported data has its own from_import(...) function that will take the data loaded by the RootImporter and load it accordingly:

RootImporter import("/path/to/root_file.root");
const auto data            = import();
const auto particle_params = ParticleParams::from_import(data);
const auto material_params = MaterialParams::from_import(data);
const auto cutoff_params   = CutoffParams::from_import(data);
// And so on
