Build this hit on the heap, but possibly starting from already allocated memory. if 'memory' is not null, it will call the placed delete, and then the placed new to make a new hit if 'memory' is null, it will fill it with a new heap-allocated hit both at entry and exit of this method any rechit in 'memory' DOES NOT own it's persistent rechit

virtual bool TSiStripMatchedRecHit::canImproveWithTrack ( ) const

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&).

drop the pointer to the hit, so that it's not deleted by the destructor. you must call this before deleting the TSiStripMatchedRecHit IF AND ONLY IF it doesn't own the rechit

TSiStripMatchedRecHit::RecHitPointer TSiStripMatchedRecHit::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.
