// G4BiasingProcessSharedData
|
|
//
|
|
// Class Description:
|
|
// This class represents the data that the G4BiasingProcessInterface
|
|
// objects attached to a same particle / hold by a same G4ProcessManager
|
|
// share. It allows the active G4BiasingProcessInterface objects to share
|
|
// information on operations that are common the these instances:
|
|
// - the current and previous G4VBiasingOperator objects (their
|
|
// pointers are collected once, at the beginning of the PostStepGPIL
|
|
// by the first interface invoked)
|
|
// - add the list of cooperating G4BiasingProcessInterface objects,
|
|
// acting on a same particle type.
|
|
// G4BiasingProcessInterface is friend class of this one.
