Josh Elser commented on ACCUMULO-2817:
--------------------------------------
bq. Hi folks, I'm interested in calling decodeUnchecked(byte[], off, len) as
public API, since it removes the need to copy a subarray out from a larger
array.
Can we pull this discussion into another JIRA issue, [~dhutchis]? It would get
confusing to track since this changeset was already released in 1.7.0.

> Similar to ACCUMULO-2445, but presently the encoder only works on complete
> byte arrays. This forces an extra copy of the data when it is located in an
> array that contains other information (e.g. a composite key).
> It would be nice to be able to provide offset and length arguments to
> {{Encoder.decode}} so that users can avoid the additional arraycopy.
> Changing to a ByteBuffer instead of byte array argument would also be
> acceptable, but more churn on the API that, unless it's happening globally, I
> would rather avoid. It would also incur the penalty for that extra Object,
> which while minimal alone, could be significant if decoding every value in a
> table, for example.
