Interface IProxGraphOptWrapper

public interface IProxGraphOptWrapper

Interface to wrap optimization helpers for proximity graph functions (see IProxGraph). Examples might include some sort of octree of the nodes and edges of the communication graph at the last evaluation point. Interface class contains no functions, other then createClone() and checkValidity(). Proximity graph functions will have to cast to the appropriate subclass and then check for null. Proximity graph functions which use optimization helpers should be able to function (albeit more slowly) without the use of optimization helpers, or by creating their own instance in the event that a valid one is not passed in.

Method Summary

boolean	checkValidity(int nDim, double[] arrPoints) Test function, check whether a vector of positions matches this set of optimization hints.
IProxGraphOptWrapper	createClone()

Method Detail

createClone

IProxGraphOptWrapper createClone()

Returns:

copy of myself cast to interface class.

checkValidity

boolean checkValidity(int nDim,
                      double[] arrPoints)

Test function, check whether a vector of positions matches this set of optimization hints. Extremely important for ensuring correct behavior. Intent is that this check is done in O(n) time, while unoptimized proximity graph calculation would take O(n^2) time or O(log(n)) time. I.E. if we're given an octree, check whether the points supplied match the octree.

Parameters:

nDim - dimensionality of individual points

arrPoints - position vector we are testing against

Returns:

boolean value indicating whether these optimization hints correspond to the position vector supplied
