virtual void avro::InputStream::backup ( size_t  len) [pure virtual]

"Returns" back some of the data to the stream.

The returned data must be less than what was obtained in the last call to next().

Referenced by avro::StreamReader::reset().

virtual size_t avro::InputStream::byteCount ( ) const [pure virtual]

Returns the number of bytes read from this stream so far.

All the bytes made available through next are considered to be used unless, retutned back using backup.

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

Returns some of available data.

Returns true if some data is available, false if no more data is available or an error has occurred.
