virtual bool TransientTrackingRecHit::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 in GenericProjectedRecHit2D, TRecHit1DMomConstraint, TRecHit2DPosConstraint, TSiPixelRecHit, TSiStripMatchedRecHit, TSiStripRecHit2DLocalPos, TSiTrackerMultiRecHit, GenericTransientTrackingRecHit, TransientTrackingRecHitByValue< RecHit >, and TransientTrackingRecHitByValue< InvalidTrackingRecHit >.

Definition at line 78 of file TransientTrackingRecHit.h.

00078 {return false;}

virtual TransientTrackingRecHit* TransientTrackingRecHit::clone (  )  const [private, pure virtual]

Implements TrackingRecHit.

Implemented in MuonTransientTrackingRecHit, GenericProjectedRecHit2D, ProjectedRecHit2D, TRecHit1DMomConstraint, TRecHit2DPosConstraint, TSiPixelRecHit, TSiStripMatchedRecHit, TSiStripRecHit2DLocalPos, TSiTrackerMultiRecHit, GenericTransientTrackingRecHit, InvalidTransientRecHit, TransientTrackingRecHitByValue< RecHit >, and TransientTrackingRecHitByValue< InvalidTrackingRecHit >.

TransientTrackingRecHit::RecHitPointer TransientTrackingRecHit::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.

Reimplemented in GenericProjectedRecHit2D, ProjectedRecHit2D, TRecHit1DMomConstraint, TRecHit2DPosConstraint, TSiPixelRecHit, TSiStripMatchedRecHit, TSiStripRecHit2DLocalPos, and TSiTrackerMultiRecHit.
