Examples of com.vividsolutions.jts.geom.GeometryFactory.createLineString()

com.vividsolutions.jts.geom.GeometryFactory.createLineString()
Creates a LineString using the given Coordinates; a null or empty array will create an empty LineString. Consecutive points must not be equal. @param coordinates an array without null elements, or an empty array, or null

                Coordinate[] c = new Coordinate[value.length];


                for (int i = 0; i < c.length; i++)
                    c[i] = (Coordinate) value[i].getValue();


                p = gf.createLineString(c);
            } else {
                if (value.length > 1) {
                    throw new SAXException(
