write method

@override void write(LByteBuffer buffer, Object geometry)

Write the geometry into the ByteBuffer. The position, byteOrder, and limit are all set. The handler is not responsible for writing the record or shape type integer.

@param buffer The ByteBuffer to write to. @param geometry The geometry to write.

Implementation

@override
void write(LByteBuffer buffer, Object geometry) {
  Point point = geometry as Point;
  Coordinate c = point.getCoordinate()!;

  buffer.putDouble64(c.x);
  buffer.putDouble64(c.y);

  if (shapeType == ShapeType.POINTZ) {
    if (c.getZ().isNaN) {
      // nan means not defined
      buffer.putDouble64(0.0);
    } else {
      buffer.putDouble64(c.getZ());
    }
  }

  if ((shapeType == ShapeType.POINTZ) || (shapeType == ShapeType.POINTM)) {
    double m = point.getCoordinateSequence().getM(0);
    buffer.putDouble64(m.isNaN ? 0.0 : m); // M
  }
}
