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&). this will be done inside the TkCloner itself
