List of all members.

Public Member Functions

virtual bool canImproveWithTrack () const
 Returns true if the clone( const TrajectoryStateOnSurface&) method returns an improved hit, false if it returns an identical copy.
virtual RecHitPointer clone (const TrajectoryStateOnSurface &ts) const
 Returns a copy of the hit with parameters and errors computed with respect to the TrajectoryStateOnSurface given as argument.
virtual const GeomDet * det () const
 The GomeDet* can be zero for InvalidTransientRecHits and for TConstraintRecHit2Ds.
virtual const GeomDetUnit * detUnit () const
 CAUTION: the GeomDetUnit* is zero for composite hits (matched hits in the tracker, segments in the muon).

virtual bool TRecHit2DPosConstraint::canImproveWithTrack (  )  const [inline, virtual]

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.

virtual RecHitPointer TRecHit2DPosConstraint::clone ( const TrajectoryStateOnSurface &  ts  )  const [inline, 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.

virtual const GeomDet* TRecHit2DPosConstraint::det (  )  const [inline, virtual]
