Interface Segmenter

All Known Implementing Classes:

AbstractSegmenter, CylindricalBarrelSegmenter, DiskToWedgesSegmenter, DiskTrackerSegmenter, DiskTrackerToRingsSegmenter, DiskTrackerToWedgesSegmenter, ExampleSegmenter1, ForwardingSegmenter, RegionSegmenter, SubdetectorBasedSegmenter

public interface Segmenter

Any class that implement this interface defines virtual segmentation of either entire detector or some part of it.

Additional machinery is provided for chaining Segmenters - see AbstractSegmenter for details.

Method Summary

Methods

Modifier and Type	Method and Description
void	detectorChanged(Detector detector) Detector dependent initialization.
Sensor	getSensor(int sensorID) Creates a new Sensor object given full SensorID.
int	getSensorID(SimTrackerHit hit) Returns integer SensorID uniquely identifying a Sensor object within the whole detector, given the simulated hit.
List<Integer>	getSensorIDs() Returns a list of SensorsIDs corresponding to all virtual segments in the part of the detector handled by this Segmenter.
List<Integer>	getStereoPartners(int sensorID) Returns a list of Sensors that might contain hits that should be combined with hits in the Sensor whose sensorID is supplied as an argument to form stereo pairs.

Method Detail

getSensorIDs

List<Integer> getSensorIDs()

Returns a list of SensorsIDs corresponding to all virtual segments in the part of the detector handled by this Segmenter.

getSensorID

int getSensorID(SimTrackerHit hit)

Returns integer SensorID uniquely identifying a Sensor object within the whole detector, given the simulated hit. Returns "-1" if the hit is outside of any sensor.

getSensor

Sensor getSensor(int sensorID)

Creates a new Sensor object given full SensorID.

detectorChanged

void detectorChanged(Detector detector)

Detector dependent initialization.

getStereoPartners

List<Integer> getStereoPartners(int sensorID)

Returns a list of Sensors that might contain hits that should be combined with hits in the Sensor whose sensorID is supplied as an argument to form stereo pairs. If an empty list is returned, hits on this sensor will be ignored when forming crosses. If null is returned, org.lcsim.contrib.onoprien.tracking.hitmaking.TrackerHitConverter will, by default, create a single 3-dimensional hit at the center of the strip.
