Detailed Description

A state with arbitrary dimension defined in a DetPlane.

The dimension and meaning of the state_ vector are defined by the track parameterization of the rep_. sharedPlane_ is a shared_pointer, the ownership over that plane is shared between all StateOnPlane objects defined in that plane. The definition of the state is bound to the TrackRep rep_. Therefore, the StateOnPlane contains a pointer to a AbsTrackRep. It will provide functionality to extrapolate it and translate the state it into cartesian coordinates. Shortcuts to all functions of the AbsTrackRep which use this StateOnPlane are also provided here.
