org.geotools.geometry.iso.coordinate.LineStringImpl
A LineString consists of sequence of line segments, each having a parameterization like the one for LineSegment. The class essentially combines a Sequence into a single object, with the obvious savings of storage space. @author Jackson Roehrig & Sanjay Jena @source $URL$
