Expose FilteredTermsEnum from MTQ
----------------------------------
Key: LUCENE-3789
URL: https://issues.apache.org/jira/browse/LUCENE-3789
Project: Lucene - Java
Issue Type: Improvement
Components: core/search
Affects Versions: 3.6, 4.0
Reporter: Simon Willnauer
Priority: Minor
Fix For: 3.6, 4.0
MTQ#getEnum() is protected and in order to access it you need to be in the
o.a.l.search package.
here is a relevant snipped from the mailing list discussion
{noformat}
getEnum() is protected so it is intended to be called *only* by subclasses
(that's the idea behind protected methods). They are also accessible by other
classes from the same package, but that's more a Java bug than a feature. The
problem with MTQ is that RewriteMethod is a separate *class* and *not a
subclass* of MTQ, so the method cannot be called (it can because of the "java
bug" called from same package). So theoretically it has to be public otherwise
you cannot call getEnum().
Another cleaner fix would be to add a protected final method to RewriteMethod
that calls this method from MTQ. So anything subclassing RewriteMethod can get
the enum from inside the RewriteMethod class which is the "correct" way to
handle it. Delegating to MTQ is then "internal".
