net.obsearch.index.bucket.sleek
Class SleekBucketDouble<O extends OBDouble>

java.lang.Object
  extended by net.obsearch.index.bucket.sleek.SleekBucketDouble<O>
All Implemented Interfaces:
net.obsearch.index.bucket.BucketContainer<O,BucketObjectDouble<O>,OBQueryDouble<O>>
public class SleekBucketDouble<O extends OBDouble>
extends Object
implements net.obsearch.index.bucket.BucketContainer<O,BucketObjectDouble<O>,OBQueryDouble<O>>

AbstractSleekBucket is designed to hold objects that belong to one bucket. The bucket will hold ALL the buckets. Optionally, objects inside the bucket can be used as pivotCount. Format: ... ... .... This bucket design focuses on pivotCount local to a partition instead of global pivotCount. Also, the storage and reading of the container is responsability of the index. The class does not access directly the index unlike the bucket.* classes we now have something that partitions the data properly.
