Class SeedTracker

java.lang.Object

org.lcsim.util.Driver

org.lcsim.recon.tracking.seedtracker.SeedTracker

Direct Known Subclasses:

IterativeSeedTracker

public class SeedTracker
extends Driver

Tracking algorithm based on forming track seeds from all 3-hit combinations, confirming this tentantive helix by requiring additional hits, and extending the track to additional layers. The operation of the algorithm is controlled by a list of SeedStrategy that define the tracker layers to be used and the cuts on the tracking algorithm.

Constructor Detail

SeedTracker

public SeedTracker()

Creates a new instance of SeedTracker

SeedTracker

public SeedTracker(List<SeedStrategy> strategylist)

Method Detail

process

protected void process(EventHeader event)

Invoke the track finding algorithm

Overrides:

process in class Driver

Parameters:

event - EventHeader for this event

See Also:

Driver.NextEventException, Driver.AbortRunException

detectorChanged

protected void detectorChanged(Detector detector)

Description copied from class: Driver

Called by the framework before process method when the detector geometry changes. This method is gauranteed to be called once before the first call to process.

Overrides:

detectorChanged in class Driver

putStrategyList

public void putStrategyList(List<SeedStrategy> strategylist)

Specifiy the strategies to be used by the SeedTracker algorithm. Invoking this method will override the default strategies defined by the DefaultStrategy class.

Parameters:

strategylist - List of strategies to be used

setSectorParams

public void setSectorParams(int nphi,
                   double dz)

setDiagnostics

public void setDiagnostics(ISeedTrackerDiagnostics d)

setTimingPlots

public void setTimingPlots(boolean timing)

setTrkCollectionName

public void setTrkCollectionName(String name)

setInputCollectionName

public void setInputCollectionName(String name)

setMaterialManagerTransform

public void setMaterialManagerTransform(ITransform3D _detToTrk)

setMaxFit

public void setMaxFit(int maxfit)

Set the maximum number of fits used to confirm or extend a seed.

Parameters:

maxfit - maximum number of fits

setBField

public void setBField(double bfield)

setReferencePoint

public void setReferencePoint(double xref,
                     double yref)

setSectorParams

public void setSectorParams(boolean sector)

setTrackCheck

public void setTrackCheck(TrackCheck trackCheck)

Set TrackCheck object to be used by the track finding algorithm. If this method is never called, no external checking of seeds and tracks is performed.

setIterativeConfirmed

public void setIterativeConfirmed(int maxfits)

Set the maximum number of iterative fits on a confirmed/extended candidate.

Parameters:

maxfits - maximum number of fits

setUseDefaultXPlane

public void setUseDefaultXPlane(boolean useDefault)

setDebug

public void setDebug(boolean _debug)

Enable or disable the debug output

Parameters:

_debug - output switch
