             Summary: Add ListOfOutputs FST Outputs, replacing UpToTwoPositiveIntOutputs
                 Key: LUCENE-4404
                 URL: https://issues.apache.org/jira/browse/LUCENE-4404
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Michael McCandless
            Assignee: Michael McCandless
         Attachments: LUCENE-4404.patch

Spinoff from LUCENE-3842.  This just generalizes the
UpToTwoPositiveIntOutputs to a list of any arbitrary output, by
wrapping any other Outputs impl.  I also made separate methods to
write/read a node-final output: since list of values can only occur on
a final node output, this impl optimizes and avoids writing an extra
byte per label for normal arc labels.

This also fixes a bug in Builder that was sometimes failing to join
multiple outputs together.
