Hi,
currently Analyzer is an abstract class. Shouldn't we make it an
Interface?
Currently that's not possible, but it will be as soon as the

method is removed (i.e. after Lucene 1.9).

Daniel, what's the use case that would make this a significant
improvement over extending and overriding the single abstract method?
Classes that implement multiple interfaces? For consistency, similar
thoughts would apply to TokenStream, IndexReader/Writer, etc. Also
note that once it's become an interface the API is effectively frozen
forever. With abstract classes the option remains open to later add
methods with a default impl. (e.g. tokenStream(String fieldName,
String text) or whatever).
Thanks,
Wolfgang.
