[jira] [Resolved] (THRIFT-3480) offer a simple approach to compute byte size of the serialized object

James E. King, III resolved THRIFT-3480.
----------------------------------------
    Resolution: Won't Fix

This can be achieved with a TMemoryBuffer (I wrote a unit test to prove it..)

{noformat}
  shared_ptr<TMemoryBuffer> memBuffer(new TMemoryBuffer());
  shared_ptr<TBinaryProtocol> binaryProtcol(new TBinaryProtocol(memBuffer));

  thrift::test::Xtruct object;
  object.i32_thing = 10;
  object.i64_thing = 30;
  object.string_thing = "who's your daddy?";

  uint32_t size = object.write(binaryProtcol.get());
  BOOST_CHECK_EQUAL(47, size);
{noformat}

> Hi Thrift guys, I would like to propose a transport for computing byte size of the serialized object.  Here is a example.
> {code}
>     boost::shared_ptr<TWriteOnlyTransport> transport{ new TWriteOnlyTransport };
>     boost::shared_ptr<TBinaryProtocol> protocol{ new TBinaryProtocol(transport) };
>     size = object.write(protocol.get());
> {code}
> A write only transport can be written but never read.  It discards all data written to it but reports that the write operation succeeded.  And the truth is that write function of this transport does nothing at all.
