// G4BiasingProcessInterface

// Class Description:
|

// A wrapper process making the interface between the tracking
|
||||
// and the G4VBiasingOperator objects attached to volumes.
|
||||
// If this process holds a physics process, it forwards
|
||||
// tracking calls to this process in volume where not biasing
|
||||
// occurs. In volumes with biasing (with a G4VBiasingOperator
|
||||
// attached) the process gets what to do messaging the biasing
|
||||
// operator :
|
||||
// - at the PostStepGPIL level, for getting an occurence biasing
|
||||
// operation. If such an operation is returned to the process
|
||||
// this operation will be messaged at several places.
|
||||
// - at the PostStepDoIt level, to get a possible final state
|
||||
// biasing operation
|
||||
// If the process does not hold a physics process, it is meant
|
||||
// as handling "non physics" biasing operations: pure splitting
|
||||
// or pure kiling for example (ie not brem splitting).
