Class BKDReader.IndexTree

  • All Implemented Interfaces:
    Enclosing class:

    public class BKDReader.IndexTree
    extends Object
    implements Cloneable
    Used to walk the off-heap index. The format takes advantage of the limited access pattern to the BKD tree at search time, i.e. starting at the root node and recursing downwards one child at a time.
    NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
