Serializing Generated objects to data file with Avro C++

[Teryl Taylor]

Hi everyone,

I'm playing around with Avro C++ and it looks pretty neat.  I generated a
class based on a JSON schema which was dropped in a header file.    What is
the best way to write out instances of these classes to a file?   The
example in the documentation shows:

 Math::complex c;
    c.real = 10.0;
    c.imaginary = 20.0;

    // Writer is the object that will do the actual I/O and buffer the results
    avro::Writer writer;

    // This will invoke the writer on my object
    avro::serialize(writer, c);



***********************************************************************************************


But it is unclear how to attach a file stream to the writer.   I also tried:

avro::compileJsonSchema(is, validSchema);
                is.close();
                dfWriter = new 
avro::DataFileWriter<GenObject>(outputdir.c_str(),
validSchema);
dfWriter->write(obj);


But this won't compile giving the error:

/terylt/Projects/bitvectors/avro-cpp-1.5.1/api/Specific.hh:195: error:
'encode' is not a member of 'avro::codec_traits<GenObject>'


What's the best way to write out my objects to disk?
