Benson Margulies commented on MAHOUT-1168:
------------------------------------------
I've revised the design of this a bit.
I've factored out an AbstractLuceneIterator, with an abstract method
org.apache.mahout.utils.vectors.lucene.AbstractLuceneIterator#getVectorName,
called at each iteration.
The plain LuceneIterator just arranges to fetch the id field, and return the
value from this method.
Other subclasses can fetch more fields and provide accessors.
> Allow access to current Lucene document from LuceneIterator
