returns the tracklength spanned in this extrapolation

There is a default implementation in GFAbsTrackRep.cxx which just drops the predicted covaraiance. If your trackrep has a way to extrapolate without giving a correct cov (that would be faster probably), please overwrite it. This method does NOT alter the state of the object!

TODO: make this faster by neglecting covariances ?

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. This method does NOT alter the state of the object!

virtual

This method is to extrapolate the track to point of closest approach to a point in space.

There is an empty implementation of this method in GFAbsTrackRep.cxx, which will just abort with an error message. One can overwrite this method if one wishes to implement a track representation, which should have this feature. An example of an experiment in which you would not need this feature would be track fitting (not so much vertexing) in an experiment with only planar trackers like silicons or planar wire chambers and such. An example where you would need it, would be a TPC where you have to fit the track to space points, or other drift chambers with complicated hit topology. This method does NOT alter the state of the object!
