Jonathan Ellis commented on CASSANDRA-4865:
-------------------------------------------
Vijay, could you take a stab at this? The bit arithmetic made my head hurt.
(may want to add a getInt method to Memory to avoid signed/unsigned messes...
then again maybe getByte is faster from native, no idea really.)
