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
