------------------------------------
Summary: HnswGraph could make use of a SparseFixedBitSet.getAndSet
Key: LUCENE-10130
URL: https://issues.apache.org/jira/browse/LUCENE-10130
Project: Lucene - Core
Issue Type: Task
Reporter: Robert Muir
Currently HnswGraph uses SparseFixedBitSet "visited" to track where it has
already been. The logic currently looks like this:
{code}
if (visited.get(entryPoint) == false) {
visited.set(entryPoint);
... logic ...
}
{code}
If SparseFixedBitSet had a {{getAndSet}} (like FixedBitSet), the code could be:
{code}
if (visited.getAndSet(entrypoint) == false) {
... logic ...
}
{code}
