…kes G4HepEmRun/include free from Geant4 headers.
Only the Geant4 specific random engine implementation stays out (stays in /src) form the G4HepEmRun/inlcude after this changes. This separates the Geant4 dependent part (i.e. the random engine specification) from the rest of the run time funtionality. All run time funtionalities, which is the complete physics required by a HEP EM shower simulation, can be utilised by an external simulation project independently from Geant4 based solely on the G4HepEmRun/includes. The external project needs to specify the random engine (by providing the implementaion left in the /src) and linked only with the g4HepEmData and g4HepEmDataJsonIO libraries for the physics data structures and their IO.

Contains a set of small modifications to ensure that
HepEmcan be utilised in external simulation projects alone, i.e. without anyGeant4(not even header) dependences. After this modifications, the content ofG4HepEmRun/includeprovides all the run time functionalities for a complete EM shower simulation alone (i.e. without any additional dependence onGeant4nor the correspondingg4HepEmRunlibrary).The external project/application needs:
G4HepEmRun/includeinG4HepEmRun/srcas that implementation isGeant4specific)g4HepEmDataandg4HepEmDataJsonIOlibraries (the former provides the data definitions used during the run while the IO makes possible to write/read these data)HepEmdata and parameter structuresThen the appropriate simulation step computations can be implemented by utilising the
G4HepEmElectronManagerandG4HepEmGammaManagerprovided byHepEmthroughG4HepEmRun/include.
