addLineSegments method
Adds the line segments defined by an array of coordinates to the linear centroid accumulators.
@param pts an array of {@link Coordinate}s
Implementation
void addLineSegments(List<Coordinate> pts) {
double lineLen = 0.0;
for (int i = 0; i < pts.length - 1; i++) {
double segmentLen = pts[i].distance(pts[i + 1]);
if (segmentLen == 0.0) continue;
lineLen += segmentLen;
double midx = (pts[i].x + pts[i + 1].x) / 2;
lineCentSum.x += segmentLen * midx;
double midy = (pts[i].y + pts[i + 1].y) / 2;
lineCentSum.y += segmentLen * midy;
}
totalLength += lineLen;
if (lineLen == 0.0 && pts.length > 0) addPoint(pts[0]);
