Detailed Description

Abstract base class for a track representation.

Provides functionality to extrapolate a StateOnPlane to another DetPlane, to the POCA to a line or a point, or a cylinder or sphere. Defines a set of parameters describing the track. StateOnPlane objects are always defined with a track parameterization of a specific AbsTrackRep. The AbsTrackRep provides functionality to translate from the internal representation of a state into cartesian position and momentum (and covariance) and vice versa.
