virtual bool TRecHit2DPosConstraint::canImproveWithTrack ( ) const

inlinevirtual

Returns true if the clone( const TrajectoryStateOnSurface&) method returns an improved hit, false if it returns an identical copy. In order to avoid redundent copies one should call canImproveWithTrack() before calling clone( const TrajectoryStateOnSurface&).

Reimplemented from TransientTrackingRecHit.

{return false;}

virtual RecHitPointer TRecHit2DPosConstraint::clone ( const TrajectoryStateOnSurface &  ts ) const

inlinevirtual

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.
