Member Function Documentation

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 TRecHit1DMomConstraint, TRecHit2DPosConstraint, TRecHit5DParamConstraint, TSiPixelRecHit, TSiStripMatchedRecHit, TSiStripRecHit1D, TSiStripRecHit2DLocalPos, TSiTrackerMultiRecHit, GenericTransientTrackingRecHit, TransientTrackingRecHitByValue< RecHit >, and TransientTrackingRecHitByValue< InvalidTrackingRecHit >.

Definition at line 88 of file TransientTrackingRecHit.h.

{return false;}

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 ProjectedRecHit2D, TRecHit1DMomConstraint, TRecHit2DPosConstraint, TRecHit5DParamConstraint, TSiPixelRecHit, TSiStripMatchedRecHit, TSiStripRecHit1D, TSiStripRecHit2DLocalPos, and TSiTrackerMultiRecHit.
