             Summary: offer a simple approach to compute byte size of the 
serialized object
                 Key: THRIFT-3480
                 URL: https://issues.apache.org/jira/browse/THRIFT-3480
             Project: Thrift
          Issue Type: New Feature
          Components: C++ - Library
    Affects Versions: 0.9.3
            Reporter: Xiaoshuang LU
             Fix For: 0.9.4


Hi Thrift guys, I would like to propose a transport for computing byte size of 
the serialized object.  Here is a example.

{{
    boost::shared_ptr<TWriteOnlyTransport> transport{ new TWriteOnlyTransport };
    boost::shared_ptr<TBinaryProtocol> protocol{ new TBinaryProtocol(transport) 
};

    size = object.write(protocol.get());
}}

A write only transport can be written but never read.  It discards all data 
written to it but reports that the write operation succeeded.
