 int superlayerId,
 int layerId)

Method Details

getMidplane

public Plane3D getMidplane()

Returns the plane that bisects the the region containing the layer. In nominal alignments, for sectors 0 and 3 this plane is in the xz-plane.

Returns:

the plane that bisects the the region containing the layer

onSetTransformation

public void onSetTransformation(Transformation3D transform)

Description copied from class: AbstractLayer

Classes extending AbstractLayer should implement onSetTransformation so that any additional geometric data they contain is transformed appropriately when AbstractLayer's onSetTransformation method is invoked. To implement this method simply apply the given transformation on all of the transformable contained in the layer that are not managed by AbstractLayer. This method is called at the end of AbstractLayer's setTransformation method.

Overrides:

onSetTransformation in class AbstractLayer<DriftChamberWire>

Parameters:

transform - the full transformation from the old coordinate system to the new coordinate system

See Also:

• Layer.setTransformation(org.jlab.geom.prim.Transformation3D)

getType

public String getType()

Returns "DC Layer".

Returns:

"DC Layer"

getHits

public List<DetectorHit> getHits(Path3D path)

Description copied from interface: Layer

Returns a list of DetecorHits which store information about intersections with components in this superlayer.

Specified by:

getHits in interface Layer<DriftChamberWire>

Overrides:

getHits in class AbstractLayer<DriftChamberWire>

Parameters:

path - the path

Returns:

a list of detector hits
