I struggle to make this work though since the changes to make everything
more typesafe have also made the interesting bits inaccessible. EG I thought of
adding something like this:
```
for (LeafReaderContext ctx : reader.leaves()) {
CodecReader codecReader = (CodecReader) ctx.reader();
HnswGraph graph = ((HnswGraphProvider)
codecReader.getVectorReader()).getGraph(vectorField);
if (HnswTestUtil.isFullyConnected(graph) == false) {
// for now just bail out.
return;
}
}
```
to `BaseVector...QueryTest` however the VectorReader returned from that is
hiding its HnswGraph behind a few layers of abstraction:
class
org.apache.lucene.codecs.perfield.PerFieldKnnVectorsFormat$FieldsReader cannot
be cast to class org.apache.lucene.codecs.HnswGraphProvider
(org.apache.lucene.codecs.perfield.PerFieldKnnVectorsFormat$FieldsReader and
org.apache.lucene.codecs.HnswGraphProvider are in unnamed module of loader
'app')
not sure what the approved way to go about this would be
