Constructor Detail

• SubLine

  public SubLine(Line line,
         IntervalsSet remainingRegion)

  Simple constructor.

  Parameters:

  line - underlying line

  remainingRegion - remaining region of the line

• SubLine

  public SubLine(Vector3D start,
         Vector3D end,
         double tolerance)
          throws MathIllegalArgumentException

  Create a sub-line from two endpoints.

  Parameters:

  start - start point

  end - end point

  tolerance - tolerance below which points are considered identical

  Throws:

  MathIllegalArgumentException - if the points are equal

  Since:

  3.3

• SubLine

  public SubLine(Vector3D start,
         Vector3D end)
          throws MathIllegalArgumentException

  Deprecated. as of 3.3, replaced with SubLine(Vector3D, Vector3D, double)
  Create a sub-line from two endpoints.

  Parameters:

  start - start point

  end - end point

  Throws:

  MathIllegalArgumentException - if the points are equal

• SubLine

  public SubLine(Segment segment)
          throws MathIllegalArgumentException

  Create a sub-line from a segment.

  Parameters:

  segment - single segment forming the sub-line

  Throws:

  MathIllegalArgumentException - if the segment endpoints are equal

Method Detail

• getSegments

  public List<Segment> getSegments()

  Get the endpoints of the sub-line.

  A subline may be any arbitrary number of disjoints segments, so the endpoints are provided as a list of endpoint pairs. Each element of the list represents one segment, and each segment contains a start point at index 0 and an end point at index 1. If the sub-line is unbounded in the negative infinity direction, the start point of the first segment will have infinite coordinates. If the sub-line is unbounded in the positive infinity direction, the end point of the last segment will have infinite coordinates. So a sub-line covering the whole line will contain just one row and both elements of this row will have infinite coordinates. If the sub-line is empty, the returned list will contain 0 segments.

  Returns:

  list of segments endpoints

• intersection

  public Vector3D intersection(SubLine subLine,
                      boolean includeEndPoints)

  Get the intersection of the instance and another sub-line.

  This method is related to the intersection method in the Line class, but in addition to compute the point along infinite lines, it also checks the point lies on both sub-line ranges.

  Parameters:

  subLine - other sub-line which may intersect instance

  includeEndPoints - if true, endpoints are considered to belong to instance (i.e. they are closed sets) and may be returned, otherwise endpoints are considered to not belong to instance (i.e. they are open sets) and intersection occurring on endpoints lead to null being returned

  Returns:

  the intersection point if there is one, null if the sub-lines don't intersect
