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

All Implemented Interfaces:

Segmenter

public class CylindricalBarrelSegmenter
extends RegionSegmenter

Simplistic Segmenter that tiles barrel cylinders with Z-parallel strips or pixels.

Each barrel layer will correspond to a single Sensor object, with the postfix equal to layer number.

Constructor Detail

CylindricalBarrelSegmenter

public CylindricalBarrelSegmenter(String subdetectorName)

Creates a new instance of CylindricalBarrelSegmenter. Subdetector name supplied to the constructor is used to provide reasonable defaults for strip width and length.

Method Detail

detectorChanged

public void detectorChanged(Detector detector)

Detector-dependent initialization.

Specified by:

detectorChanged in interface Segmenter

Overrides:

detectorChanged in class RegionSegmenter

setStripWidth

public void setStripWidth(double pitch)

Set strip width. Default is 5 micron.

setStripLength

public void setStripLength(double length)

Set strip length. Default is 10 cm.

makePostfix

public int makePostfix(SimTrackerHit hit)

Returns sensor ID postfix corresponding to the given position. This postfix must be positive integer, unique within the part of the detector handled by this Segmenter object. The final Sensor ID will be constructed taking into account the prefix set through a call to RegionSegmenter.setPrefix(int, int) method.

Specified by:

makePostfix in class RegionSegmenter

getMaxPostfix

public int getMaxPostfix()

Returns maximum postfix value that can be returned by makePostfix(SimTrackerHit) method of this Segmenter.

Specified by:

getMaxPostfix in class RegionSegmenter

makeSensor

public Sensor makeSensor(int postfix)

Creates a Sensor object given the ID.

Specified by:

makeSensor in class RegionSegmenter

getStereoPartners

public List<Integer> getStereoPartners(int sensorID)

Returnes null since there is no stereo in cylindrical barel.

Specified by:

getStereoPartners in interface Segmenter

Overrides:

getStereoPartners in class RegionSegmenter
