Xiaoshuang LU updated THRIFT-3480:
----------------------------------
    Description: 
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.
