All Implemented Interfaces:

Comparable<BucketObjectFloat>

public class BucketObjectFloat<O extends OBFloat>
extends BucketObject<O>
implements Comparable<BucketObjectFloat>

BucketObjectFloat extends BucketObject by adding an SMAP vector used to minimize the number of distance computations required per object.
