Kenny MacLeod commented on LUCENE-685:
--------------------------------------

Interfaces in APIs are hard to manintain...  you *are* kidding, right?  Take a look at every well-written Java API out there, they *all* make heavy use of interfaces, because it makes API maintenance *easier*.

Never mind.  Now that Spring has a Lucene API wrapper, I can use that to get a usable API.

> org.apache.lucene.index.IndexWriter should probably implement an interface to allow us to more easily write unit tests that use it.  As it stands, it's a complex class that's hard to stub/mock.
> For example, an interface which had methods such as addDocument(), close() and optimize().
