Method Details

getNeighborsIterator

public NodesIterator getNeighborsIterator(int ordinal)

Description copied from interface: GraphIndex.View

Iterator over the neighbors of a given node. Only the most recently instantiated iterator is guaranteed to be valid.

Specified by:

getNeighborsIterator in interface GraphIndex.View

size

public int size()

Specified by:

size in interface GraphIndex.View

Returns:

the number of nodes in the graph

entryNode

public int entryNode()

Specified by:

entryNode in interface GraphIndex.View

Returns:

the node of the graph to start searches at

liveNodes

public Bits liveNodes()

Description copied from interface: GraphIndex.View

Return a Bits instance indicating which nodes are live. The result is undefined for ordinals that do not correspond to nodes in the graph.

Specified by:

liveNodes in interface GraphIndex.View

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException

rerankerFor

public ScoreFunction.Reranker rerankerFor(VectorFloat<?> queryVector,
 VectorSimilarityFunction vsf)

Specified by:

rerankerFor in interface GraphIndex.ScoringView

approximateScoreFunctionFor

public ScoreFunction.ApproximateScoreFunction approximateScoreFunctionFor(VectorFloat<?> queryVector,
 VectorSimilarityFunction vsf)

Specified by:

approximateScoreFunctionFor in interface GraphIndex.ScoringView
