Member Function Documentation

canImproveWithTrack()

bool TValidTrackingRecHit::canImproveWithTrack ( ) const

inlineoverridevirtual

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 TrackingRecHit.

Definition at line 51 of file TValidTrackingRecHit.h.

{ return false; }

clone()
