Michael McCandless commented on LUCENE-2958:
--------------------------------------------
bq. If we do the header idea, then we'll need to move to a more generic
DocData. So instead of doing docData.title = title, you'll need to do
docData.set("title", title), which under the hood will store that pair in a Map
or Properties. Similarly for 'getter'. That also has some implications on perf.
Hmm, true.
Really, it would be better if LineDocSource could directly set Field values.
Then, up front on parsing the header it could make a Field[], and then when
parsing the line it'd just set these Field values.
But that's a much larger change... so I think until then we should just pass
the full String line to eg a processLine method? And the default optimized one
breaks it into the fixed name/date/body fields.
