Alan Woodward updated LUCENE-6371:
----------------------------------
Attachment: LUCENE-6371.patch
Here's a patch taking into account all the comments here and on LUCENE-6494.
* SpanCollector becomes an interface again, so payload collection is entirely
defined in the .payloads package
* BufferedSpanCollector is removed, replaced by a simple array of
SpanCollectors in NearSpansOrdered. SpanCollector has two methods to deal with
this, newSubCollectors() and collectedComposite(), to create and then replay.
* SpanCollectors are passed through in getSpans(). A null passed here means no
collection, and there's a default getSpans() call on SpanWeight that always
passes a null collector.
* I've removed SpanSimilarity, in favour of passing a map of Terms to
TermContexts to the SpanWeight constructor. If this is null, then scoring
isn't required; if not, then SpanWeight builds a SimScorer and passes that to
its scorer.
