: These are "read only" interfaces exposed to users as a part of the : API. They never implement but use them a lot so they have to be : public
Yeah, but there's no such thing as a "read only" interface :) ... even if you can't think of a reason why someone would implement your interface, if it's public they might, and then they might complain that their app doesn't compile when they upgrade from Solr 1.3.0 to Solr 1.3.1 becuase you added a method to it. it's silly, i agree, but it's happened ... more then once, which is why the safe thing to do is add a simple javadoc comment in cases like this .... "Note: This interface is not intended to be implemented by third party code, it may change without warning." -Hoss
