1. trait DistanceMeasure[M, D <: Space[D]] extends AnyRef

   

   A DistanceMeasure is used in nearest neighbour search, in order to allow different ways points and children are favoured or filtered during the search.

   A DistanceMeasure is used in nearest neighbour search, in order to allow different ways points and children are favoured or filtered during the search.

   For simplicity and performance, the measures, although they could be generalized as Ordered, are given as Long values. Only comparisons are performed with the results, therefore some optimizations may be made, for example the euclidean measure omits taking the square root of the distances, while still preserving the ordering between the possible results.

2. trait HyperCube[D <: Space[D]] extends AnyRef

   

3. final case class IntCube(cx: Int, cy: Int, cz: Int, extent: Int) extends IntCubeLike with Product with Serializable

   

4. trait IntCubeLike extends HyperCube[ThreeDim] with QueryShape[BigInt, ThreeDim]

   

   A three dimensional cube.

   A three dimensional cube.

   Wikipedia: "Usually, the octant with all three positive coordinates is referred to as the first octant. There is no generally used naming convention for the other seven octants."

   However the article suggests (given that we count from zero): - 0 (binary 000) - top-front-left - 1 (binary 001) - top-back-right - 2 (binary 010) - top-back-left - 3 (binary 011) - top-front-left - 4 (binary 100) - bottom-front-left - 5 (binary 101) - bottom-back-left - 6 (binary 110) - bottom-back-right - 7 (binary 111) - bottom-front-right

   Obviously there is no clear connection between the orientation and the binary representation. We thus prefer to chose the the octants numbering in a binary fashion, assigning bit 0 to the x-axis, bit 1 to the y-axis, and bit 2 to the z-axis, where top-front-left is 000, hence:

   - 0 (binary 000) - left-top-front - 1 (binary 001) - right-top-front - 2 (binary 010) - left-bottom-front - 3 (binary 011) - right-bottom-front - 4 (binary 100) - left-top-back - 5 (binary 101) - right-top-back - 6 (binary 110) - left-bottom-back - 7 (binary 111) - right-bottom-back

5. final case class IntHyperCubeN(components: IndexedSeq[Int], extent: Int) extends IntHyperCubeNLike with Product with Serializable

   

6. sealed trait IntHyperCubeNLike extends HyperCube[NDim] with QueryShape[BigInt, NDim]

   

7. final case class IntHyperRectangleN(components: IndexedSeq[(Int, Int)]) extends IntHyperRectangleNLike with Product with Serializable

   

   An n-dimensional hyper rectangular.

   An n-dimensional hyper rectangular.

   components

   pairs of minimum and maximum coordinates for each dimension. In each tuple, _1 must be <= _2. The maximum coordinates are inclusive (defining the maximum coordinate **within** the shape), thus it is not possible to create rectangles with side lengths of zero.

8. trait IntHyperRectangleNLike extends QueryShape[BigInt, NDim]

   

   An n-dimensional rectangular query shape.

9. final case class IntPoint2D(x: Int, y: Int) extends IntPoint2DLike with Product with Serializable

   

10. trait IntPoint2DLike extends AnyRef

13. final case class IntPointN(components: IndexedSeq[Int]) extends IntPointNLike with Product with Serializable

    

14. trait IntPointNLike extends AnyRef

    

15. final case class IntRectangle(left: Int, top: Int, width: Int, height: Int) extends IntRectangleLike with Product with Serializable

    

16. trait IntRectangleLike extends QueryShape[Long, TwoDim]

    

    A 2D rectangular query shape.

17. final case class IntSquare(cx: Int, cy: Int, extent: Int) extends IntSquareLike with Product with Serializable

    

18. trait IntSquareLike extends HyperCube[TwoDim] with QueryShape[Long, TwoDim]

20. trait LongPoint2DLike extends AnyRef

    

21. final case class LongRectangle(left: Long, top: Long, width: Long, height: Long) extends LongRectangleLike with Product with Serializable

    

22. trait LongRectangleLike extends QueryShape[BigInt, TwoDim]

    

    A 2D rectangular query shape.

23. final case class LongSquare(cx: Long, cy: Long, extent: Long) extends LongSquareLike with Product with Serializable

    

24. trait LongSquareLike extends HyperCube[TwoDim] with QueryShape[BigInt, TwoDim]

    

25. trait QueryShape[Area, D <: Space[D]] extends AnyRef

    

    A shape for range queries.

    A shape for range queries. Type A indicates the results of area calculations, and may be specialized.

26. trait Space[D <: Space[D]] extends AnyRef

    

    A Space abstracts over the number of dimensions that are used for point and hypercube operations.

    Big thanks to Aleksey Nikiforov for figuring out how to plug the types together...
