    Composes this distance so that a threshold is applied to point-point distances.

    Composes this distance so that a threshold is applied to point-point distances. If the point-point distance of the underlying measure returns a value less than or equal the given threshold, then instead the value 0L is returned. This allows for quicker searches so that a nearest neighbour becomes an approximate nn within the given threshold (the first arbitrary point encountered with a distance smaller than the threshold will be returned).

    Note that the threshold is directly compared to the result of distance, thus if the underlying measure uses a skewed distance, this must be taken into account. For example, if euclideanSq is used, and points within a radius of 4 should be approximated, a threshold of 4 * 4 = 16 must be chosen!

    Applies a filter to this measure by constraining distances to objects b which lie within the given IntSquare.

    Applies a filter to this measure by constraining distances to objects b which lie within the given IntSquare. That is, if for example distance( a, b ) is called, first it is checked if b is within hyperCube. If so, the underlying measure is calculated, otherwise, Long.MaxValue is returned. This behaviour extends to the minDistance and maxDistance methods.

    Calculates the maximum distance between a point and any possible point of a given hyper-cube.

    Calculates the maximum distance between a point and any possible point of a given hyper-cube. In the euclidean case, this is the distance to the hyper-cube b's corner that is furthest to the point a, no matter whether a is contained in b or not.

    Calculates the minimum distance between a point and any possible point of a given hyper-cube.

    Calculates the minimum distance between a point and any possible point of a given hyper-cube. In the euclidean case, this is the distance to the hyper-cube b's corner that is closest to the point a, if a lies outside of b, or zero, if a lies within b.
