ProjectedRecHit2D::RecHitPointer ProjectedRecHit2D::clone ( const TrajectoryStateOnSurface & ts ) const [virtual]

Returns a copy of the hit with parameters and errors computed with respect to the TrajectoryStateOnSurface given as argument. For concrete hits not capable to improve their parameters and errors this method returns an exact copy, and is equivalent to clone() without arguments.

FIXME: should report the problem somehow
