Bryan Duxbury updated THRIFT-751:
---------------------------------
Attachment: thrift-751.patch
This adds a clear() method to the TBase interface and updates TUnion and the
Java generator to supply implementations.
I did a quick microbenchmark to test performance of allocating new objects
versus clearing one existing one, and found clearing to be about 5x as fast.

> It'd be very handy to be able to quickly empty out a Thrift struct. This
> would allow one to reuse a Thrift struct reliably. In the Hadoop context,
> this would lead to a respectable performance benefit.
