make GenericArray reversible
----------------------------
Key: AVRO-540
URL: https://issues.apache.org/jira/browse/AVRO-540
Project: Avro
Issue Type: New Feature
Components: java
Affects Versions: 1.3.2
Reporter: Eric Evans
Priority: Minor
There are a number of RPC methods in Cassandra that return ordered results
(ordered by pluggable comparators, avro's ordering won't work), and each has a
means of specifying that the order be reversed. The way this is currently done
is to use a List to process the results, Collections.reverse() to reorder if
needed, and then copy them to a GenericArray to be returned. It would be nice
to avoid this intermediary step.
The patch that follows adds a reverse() method to GenericData.Array that simply
reverses the order of the elements in the underlying Object[].
