Block KD-tree, implementing the generic spatial data structure described in
this paper.
|
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. |
