Detailed Description
StiLocalTrackSeedFinder is a concrete implementation of StiTrackFinder. It is built from a collection of StiDetectorObjects, which it stores in a vector and orders properly, then uses each detector as a layer from which a one-point seed can be generated. It then proceeds to step inwards, iteratively making a local decision at each step.Definition at line 29 of file StiLocalTrackSeedFinder.h.
Member Function Documentation
| bool StiLocalTrackSeedFinder::extendHit | ( | StiHit & | hit | ) | [protected] |
Extend hit looking for closest neighbor in z.
Extend the track seed starting from the given hit. The extension proceeds from the outside-in. It stops whenever the inner most detector hits have been used.

| StiTrack * StiLocalTrackSeedFinder::findTrack | ( | double | rMin = 0 |
) | [virtual] |
Produce the next track seed Loop through available hits and attempt to form a track seed Only use hits that have not been already used in fully formed tracks.
Implements StiTrackFinder.

| StiKalmanTrack * StiLocalTrackSeedFinder::makeTrack | ( | StiHit * | hit | ) | [protected] |
