Detailed Description

Base class for all CompetingRIOsOnTack implementations, extends the common MeasurementBase.

This class is used e.g. by the Deterministic Annealing Filter to handle several RIO_OnTracks in one "effective detector layer" (might be more than one DetectorElement), which compete against each other in being assigned to a track. localParameters() and localErrorMatrix() should return the mean values according to the weights (assignment probabilities).

Effective LocalParameters, an ErrorMatrix and a number of competing ROTs with their assignment probabilities are the commonalities of all CompetingRIOsOnTrack.

The derived classes can overwrite the base class definitions of Trk::RIO_OnTrack and Trk::Surface with derived classes for internal use and to avoid extensive RTTI.

The Surface is chosen not to be a private member of the base class, such that dedicated Segments can save specific Surface types and overwrite the return type by a child class to avoid extensive RTTI.

Access to any information of the contained ROTs, such as the underlying Trk::PrepRawData, the pointer to the Trk::DetectorElementBase such as identifiers have to be retrieved from the ROT itself.
