Ryan Leary created ACCUMULO-2825:
------------------------------------

             Summary: WholeRowIterator should be extendable
                 Key: ACCUMULO-2825
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2825
             Project: Accumulo
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.6.0, 1.5.1
            Reporter: Ryan Leary
            Assignee: Ryan Leary
             Fix For: 1.6.1, 1.7.0


It would be useful to be able to choose encodings other than what is implemented already in
WholeRowIterator's encodeRow and decodeRow public static final methods.

As an example, I wrote an iterator that reads in CQ/val pairs and automatically populates
a protocol buffer. To do this, however, I essentially copy/pasted all of the WholeRowIterator
source and changed the encode/decode methods.

In the interest of not changing the WholeRowIterator API in any meaningful way (hopefully
meaning this improvement could be added to 1.6.1), I have created a new abstract iterator:
RowEncodingIterator, which WholeRowIterator now extends, implementing rowEncoder and rowDecoder.
