◆ SetMaterialCacheFile()

void cbm::kf::TrackingGeoSetupFactory::SetMaterialCacheFile	(	const TString &	filename,
		size_t	geoHash )

inlineprivate

Sets the material budget cache file name.

Parameters

filename	Material budget cache file name
geoHash	A hash of the geometry

If provided, the instance will try to read the material budget maps from the file. If the file does not exist,or the geometry hash was changed since the last time (reference hash differs from the one read from the file), a warning will be produced, the material budget maps will be recreated on the fly and they will be stored again to the file (meaning a new cache file will be generated over the existing one).
