Subject [jira] Commented: (LUCENE-743) IndexReader.reopen()

Yonik Seeley commented on LUCENE-743:
-------------------------------------

Having a read-only IndexReader would (should?) mean being able to remove "synchronized" from
some things like isDeleted()... a nice performance win for multi-processor systems for things
that didn't have access to the deleted-docs bitvec.

> If our goal is to make them read-only (we can delete via IndexWriter already)

But you can only delete-by-term.
It's more powerful to be able to delete by docid, however I manage to come up with it.
So I think deleteDocument(int id) should either be moved to a subclass.  same with setNorms?

> This is Robert Engels' implementation of IndexReader.reopen() functionality, as a set
of 3 new classes (this was easier for him to implement, but should probably be folded into
the core, if this looks good).
