Class NeighborArray


  • public class NeighborArray
    extends Object
    NeighborArray encodes the neighbors of a node and their mutual scores in the HNSW graph as a pair of growable arrays. Nodes are arranged in the sorted order of their scores in descending order (if scoresDescOrder is true), or in the ascending order of their scores (if scoresDescOrder is false)
    NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
