14. Code Review (1) ● Covers several issues discussed at Catania. Group effort required. – Integer A and Z ● plan agreed to in Catania, Gunter Folger to initiate, first integer methods by June 2010 – Cleanup of G4HadronicProcess, including removal of apparently unused testing methods, replacement of G4HadronicWhiteBoard with DumpState, removal of G4HadReentrantException, removal of unnecessary exceptions ● first version done, testing underway, Vladimir Ivantchenko, (March 2010) – E/p conservation testing in G4HadronicProcess ● first version done, improvements to follow, Dennis Wright (March 2010) 14
