28 // 20100409 M. Kelsey -- Drop unused string argument from ctors.
29 // 20110721 M. Kelsey -- Add model ID as optional ctor argument (so subclasses
30 // don't have to call SetModel()).
31 // 20110922 M. Kelsey -- Add stream argument to printParticle() => print()
32 // 20130620 M. Kelsey -- Address Coverity #37504, check self in op=()
33 // 20130806 M. Kelsey -- Per A. Dotti, move empty G4DynPart to file scope to
34 // address thread-collision problem.
35 // 20140310 M. Kelsey -- Fix constness in G4PD* passing
