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.
int charge () const
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 bool TRecHit1DMomConstraint::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&).

virtual RecHitPointer TRecHit1DMomConstraint::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.
