public class PolyLineSelectionListener extends Object implements PolylineListener
Listener that selects all features of the active and vector layers which
intersect with the defined polyline in the associated MapControl
object.
The selection will be produced after user finishes the creation of the polyline.

public void points(MeasureEvent event) throws BehaviorException
PolylineListener
Called when user moves the mouse after selecting a vertex of the polyline.
Each kind of polyline listener calculates different information with the data of the
MeasureEvent
, according its nature.
