28 // Class Description:
29 //
30 // This class represents the data that the G4BiasingProcessInterface
31 // objects attached to a same particle / hold by a same G4ProcessManager
32 // share. It allows the active G4BiasingProcessInterface objects to share
33 // information on operations that are common the these instances:
34 // - the current and previous G4VBiasingOperator objects (their
35 // pointers are collected once, at the beginning of the PostStepGPIL
36 // by the first interface invoked)
37 // - add the list of cooperating G4BiasingProcessInterface objects,
38 // acting on a same particle type.
39 // G4BiasingProcessInterface is friend class of this one.
