pyg4ometry.gdml.Reader.isComment(node)

class pyg4ometry.gdml.Reader.Reader(fileName, registryOn=True, skipMaterials=False, reduceNISTMaterialsToPredefined=False)

Read a GDML file.

Parameters:

• fileName (str) – path to gdml file to load

• registryOn (bool) – whether to build a registry

• reduceNISTMaterialsToPredefined (bool) – change NIST-named materials to predefined ones

When loading a GDML file that was exported by Geant4, the NIST materials may be fully expanded to include their full element / isotope composition. With the reduceNISTMaterialsToPredefined flag set to True, these will be ignored and the materials that have a name that matches a NIST one will be ‘reduced’ back to a predefined material by name only.

_makeMaterials(materials, elements, isotopes)

Construct the isotopes, elements and materials in that order. These aren’t returned, but simply constructed in and therefore exist in the registry.
