Class DiskTrackerSegmenter

java.lang.Object

org.lcsim.recon.tracking.vsegment.geom.AbstractSegmenter

org.lcsim.recon.tracking.vsegment.geom.ForwardingSegmenter

org.lcsim.recon.tracking.vsegment.geom.segmenters.DiskTrackerSegmenter

All Implemented Interfaces:

Segmenter

Direct Known Subclasses:

DiskTrackerToWedgesSegmenter

public abstract class DiskTrackerSegmenter
extends ForwardingSegmenter

Forwarding segmenter that chooses daughter segmenter based on the IDetectorElement associated with the hit. Daughter segmenters are prefixed in the order of increasing Z of the disks they handle. Subclasses should implement assignSegmenter(IDetectorElement) method that assigns segmenters to disks.

Method Detail

chooseSegmenter

public AbstractSegmenter chooseSegmenter(SimTrackerHit hit)

Returns daughter Segmenter that can handle the given hit.

Specified by:

chooseSegmenter in class ForwardingSegmenter

detectorChanged

public void detectorChanged(Detector detector)

Description copied from class: ForwardingSegmenter

Detector dependent initialization. Subclasses should override this method if they need to perform any detector dependent initialization, but they should call ForwardingSegmenter.updateDaughterSegmenters(Detector) from this method to have their daughter Segmenters initialized as well.

Specified by:

detectorChanged in interface Segmenter

Overrides:

detectorChanged in class ForwardingSegmenter

assignSegmenter

public abstract AbstractSegmenter assignSegmenter(IDetectorElement de)

Subclasses should implement this method to return Segmenter that handles hits in the given DetectorElement.

getLayer

public int getLayer(IDetectorElement de)

Returns layer number for the disk.

getSuperlayer

public int getSuperlayer(IDetectorElement de)

Returns superlayer number for the disk. Superlayer is a pair of sensor disks on opposite sides of the same support disk.

isInner

public boolean isInner(IDetectorElement de)

Returns true if the disk is on the side of a superlayer that faces the center of the detector.

getOtherSideIndex

protected int getOtherSideIndex(int daughterIndex)
