Uwe Schindler commented on LUCENE-5690:
---------------------------------------

bq. MultiTermsEnum and MultiDocsEnum both expose their subs

I don't see this in the code of MultiTermsEnum. Both have the arrays private and MultiTermsEnum has no getter (at least in trunk). MultiDocsEnum has a getter (not sure why). In MultiTermsEnum there is one public getter, but this one returns a package private class, so unuseable to the user (this is a bug) - should be removed.

This patch is fine if you make the methods return List<Terms> and List<ReaderSlice>, both with {{Collections.unmodifiableList(Arrays.asList(...))}}. But ReaderSlice is also a more or less "private" class (its just public for cross-package access).

What's the reason to have those public at all?

> MultiTermsEnum and MultiDocsEnum both expose their subs.  It would be useful to do the same for MultiTerms.
