Shai Erera commented on LUCENE-2958:
------------------------------------
A thought -- how about we do the following:
# LineDocSource remains basically as it is today, with a getDocData(String
line) extendable method for whoever wants
# Instead of introducing those Fillers, you create a HeaderLineDocSource which
assumes the first line read is the header line, and parses the following ones
as appropriate. It will create LDS extending getDocData.
This will not introduce a Filler in LDS, and those who don't care about it
don't need to know about it at all. Also, it will showcase the 'extendability'
of LDS.
Will that be simpler?
