numDimensions

public int numDimensions()

Description copied from interface: EuclideanSpace

Gets the space's number of dimensions.

Specified by:

numDimensions in interface EuclideanSpace

search

public void search(RealLocalizable reference)

Description copied from interface: NearestNeighborSearch

Perform nearest-neighbor search for a reference coordinate.

Specified by:

search in interface NearestNeighborSearch<T>

getPosition

public RealLocalizable getPosition()

Description copied from interface: NearestNeighborSearch

Access the position of the nearest neighbor, ordered by square Euclidean distance.

Specified by:

getPosition in interface NearestNeighborSearch<T>
