Method Detail

build
OnHeapHnswGraph build(int maxOrd) throws IOException
Adds all nodes to the graph up to the providedmaxOrd.- Parameters:
maxOrd- The maximum ordinal (excluded) of the nodes to be added.- Throws:
IOException
-
addGraphNode
void addGraphNode(int node) throws IOExceptionInserts a doc with vector value to the graph- Throws:
IOException
-
setInfoStream
void setInfoStream(InfoStream infoStream)
Set info-stream to output debugging information
-
getGraph
OnHeapHnswGraph getGraph()
-
getCompletedGraph
OnHeapHnswGraph getCompletedGraph() throws IOException
Once this method is called no further updates to the graph are accepted (addGraphNode will throw IllegalStateException). Final modifications to the graph (eg patching up disconnected components, re-ordering node ids for better delta compression) may be triggered, so callers should expect this call to take some time.- Throws:
IOException
