                                                                                        java.awt.geom.Rectangle2D box,

Returns all geometry segment points that are inside the input box. Applies to line string and polygon geometries. Just linear segments are considered (arcs, circles, isolated points, rectangles are not used).

Parameters:

geometry - the geometry object

box - the area to check for segments points that are inside.

segmentTree - a Rtree index for geometry segments. If null, it will be computed inside this method.

segmentId - a key value (can be a feature key) to be assigned to segment.

Returns:

an array of segment point for this feature.
