Namespaces

Name
allpix Helper class to hold support layers for a detector model.

Classes

	Name
class	allpix::RNGWrapper This class is a wrapper that allows to pass the per-thread random number engine from Geant4 to CRY. The Geant4 engine is seeded by the Allpix Squared framework for every event, and separately per thread, so using this engine in CRY ensures a reproducible and thread-safe simulation.

Attributes

	Name
thread_local double(T::*)()	RNGWrapper
