com.vividsolutions.jts.geom.LineString
Models an OGC-style LineString. A LineString consists of a sequence of two or more vertices, along with all points along the linearly-interpolated curves (line segments) between each pair of consecutive vertices. Consecutive vertices may be equal. The line segments in the line may intersect each other (in other words, the linestring may "curl back" in itself and self-intersect. Linestrings with exactly two identical points are invalid.
A linestring must have either 0 or 2 or more points. If these conditions are not met, the constructors throw an {@link IllegalArgumentException} @version 1.7
