Classes in org.apache.lucene.util.bkd used by org.apache.lucene.util.bkd

Class and Description
BKDConfig Basic parameters for indexing points on the BKD tree.
BKDRadixSelector.PathSlice Sliced reference to points in an PointWriter.
BKDReader Handles intersection of an multi-dimensional shape in byte[] space with a block KD-tree previously written with BKDWriter.
BKDReader.IndexTree Used to walk the off-heap index.
BKDReader.IntersectState Used to track all state for a single call to BKDReader.intersect(org.apache.lucene.index.PointValues.IntersectVisitor).
HeapPointWriter Utility class to write new points into in-heap arrays.
OfflinePointReader Reads points from disk in a fixed-with format, previously written with OfflinePointWriter.
PointReader One pass iterator through all points previously written with a PointWriter, abstracting away whether points are read from (offline) disk or simple arrays in heap.
PointValue Represents a dimensional point value written in the BKD tree.
PointWriter Appends many points, and then at the end provides a PointReader to iterate those points.
