Extrapolates the track to the given detectorplane.

Results are put into statePred and covPred This method does NOT alter the state of the object!

This changes the state and cov and plane of the rep.

This method extrapolates to to the plane and sets the results of state, cov and also plane in itself.

This method extrapolates to the point of closest approach to a line.

This method extrapolates to the POCA to a line, i.e. a wire. There is a default implementation just like for the extrapolateToPoca for trackReps which do not need this feature, which will abort the execution if it is ever called.
