ImmutablePart::getEndPoint doesn’t return the last point

HenrikPierrou

Hi,

The last point when iterating over the points in an ImmutablePart is not the point returned in getEndPoint() on that same ImmutablePart. See my example below. Why is that? I'm on ArcGIS Runtime for Android 100.0.0.

private void partTest(ImmutablePart part) {
   for (int i = 0; i < part.getPointCount(); i++) {
      Point p = part.getPoint(i);
      System.out.println(i + " - " + p.getX() + ", " + p.getY());
   }

   Point startPoint = part.getStartPoint();
   System.out.println("Start point - " + startPoint.getX() + ", " + startPoint.getY());

   Point endPoint = part.getEndPoint();
   System.out.println("End point - " + endPoint.getX() + ", " + endPoint.getY());
}

Printouts when running the above with a ImmutablePart over Stockholm:

I/System.out: 0 - 2000955.7131845958, 8217577.284820005
I/System.out: 1 - 1989299.2266646507, 8248738.619869451
I/System.out: 2 - 2011153.6917361675, 8252952.245694454
I/System.out: Start point - 2000955.7131845958, 8217577.284820005
I/System.out: End point - 1989299.2266646507, 8248738.619869451

Hi Henrik - I'm assuming you have got your ImmutablePart from a Polyline? I can repro that bug as you described. If you get the ImmutablePart from a Polygon, then you should find that the ImmutablePart.getEndPoint is the same as the last Point from ImmutablePart.getPoint(i). (I just double-checked the Segments and in both cases I find Segment.StartPoint and SegmentEndPoint are returning the expected Points.)

Thanks for finding and reporting this, I will enter this as an issue for us to address.

Regards,
