All Implemented Interfaces:

Comparable<BucketObjectLong>

public class BucketObjectLong<O extends OBLong>
extends BucketObject<O>
implements Comparable<BucketObjectLong>

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