Manuel Simoni created AVRO-1203:
-----------------------------------

             Summary: Support for obtaining the number of bytes written
                 Key: AVRO-1203
                 URL: https://issues.apache.org/jira/browse/AVRO-1203
             Project: Avro
          Issue Type: Improvement
          Components: c++
    Affects Versions: 1.7.2
            Reporter: Manuel Simoni


I've used the Avro C++ library to implement Avro support for Node.js [1].

In the course of this, I needed to extend the library so that it keeps
track of the number of bytes written to a stream by an encoder.

These changes mostly required making various headers public, and only
small changes to implementation code.

Here's a detailed list of changes:

- Make the following headers public:
  - BinaryEncoder.hh
  - Symbol.hh
  - ValidatingCodec.hh
  - json/JsonDom.hh
  - json/JsonEncoder.hh
  - json/JsonIO.hh
- Extend StreamWriter to keep track of number of bytes written (bytesWritten_, getBytesWritten())
- Expose BinaryEncoder's and JsonEncoder's StreamWriter via getStreamWriter() method

The complete changes can be viewed here on Github:

https://github.com/manuel/avro-cpp/commit/f77c108a04fc9e39397eb2fae86b2710b64e2c8a

The code is available in the "manuel/avro-cpp" Github Repo on the
"upstream_submit" branch:

https://github.com/manuel/avro-cpp/tree/upstream_submit

We would love to have this functionality added to the Avro C++ library.
