Here is the caller graph for this function:

void ActsExamples::Geant4::HepMC3::SteppingAction::UserSteppingAction ( const G4Step *  step )

override

Interface Method doing the step and records the data.

Parameters

step	is the Geant4 step of the particle

Store the step such that a vertex knows the position and upcoming process for a particle. The particle properties are stored as ingoing before and as outgoing after the step with the process was performed. Therefore the vertex defines the starting point of a process while the next vertex describes the state after the process, including all particles produced along the step. In total the entire event is represented by vertices which describe each step in Geant4.
