// File name:     G4GeneralParticleSourceData.hh
//
// Author:        Andrew Green
//
// Creation date: 20 Mar 2014
//
// Class Description:
// This class uses the singleton pattern to create a single copy of the data
// needed for the G4GPS class. As yet, only the largest parts have been split
// off.
//
// Thread Safety:
// Singleton creation (G4GeneralParticleSourceData::Instance()) is thread safe.
// Getters are thread-safe if no other thread is adding/deleting a source or normalizing
// However please note that the setters are usually accessed via messenger. This should be
// instantiated in master thread.
//
// For convinience Lock and Unlock methods are provided that can be used to serialize calls.
// For example:
//    gpsdata=G4GeneralParticleSourceData::Instance();
//    gpsdata->Lock();
//    gpsdata->AddASource(1.0);
//    gpsdata->Unlock();
