- - ### Uses of HnswGraph.NodesIterator in org.apache.lucene.util.hnsw

    Subclasses of HnswGraph.NodesIterator in org.apache.lucene.util.hnsw
    Modifier and Type | Class | Description
    --- | --- | ---

    Methods in org.apache.lucene.util.hnsw that return HnswGraph.NodesIterator
    Modifier and Type | Method | Description
    --- | --- | ---
    `abstract HnswGraph.NodesIterator` | HnswGraph.`getNodesOnLevel​(int level)` | Get all nodes on a given level as node 0th ordinals
    `HnswGraph.NodesIterator` | OnHeapHnswGraph.`getNodesOnLevel​(int level)` | WARN: calling this method will essentially iterate through all nodes at level 0 (even if you're not getting node at level 0), we have built some caching mechanism such that if graph is not changed only the first non-zero level call will pay the cost.
