Member Function Documentation

virtual uint64_t avro::OutputStream::byteCount (  )  const [pure virtual]

Number of bytes written so far into this stream.

The whole buffer returned by next() is assumed to be written unless some of it was retutned using backup().

virtual bool avro::OutputStream::next ( uint8_t **  data,
size_t *  len 
) [pure virtual]

Returns a buffer that can be written into.

On successful return, data has the pointer to the buffer and len has the number of bytes available at data.
