What is the corresponding class for org.apache.lucene.codecs.memory.DirectDocValuesFormat in Lucene9

Hi, Lucene experts:

I'm looking at some code which is based on an older version of lucene.

And I just noticed that,
the org.apache.lucene.codecs.memory.DirectDocValuesFormat
doesn't have a corresponding class in Lucene9.

But the "DirectPostingFormat" is still in Lucene9.

Could anyone help me to understand how to replace the DirectDocValueFormat
in Lucene9?

Thanks
Regards
MyCoy

Hello, MyCoy.

It seems it's gone.
https://lucene.apache.org/core/9_0_0/MIGRATE.html
https://issues.apache.org/jira/browse/LUCENE-8917
I think it's substituted by
https://lucene.apache.org/core/9_0_0/core/org/apache/lucene/codecs/lucene90/Lucene90DocValuesFormat.html
