Detailed Description
A no-copy input stream.
Member Function Documentation
◆ backup()
|
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::drain(), and avro::StreamReader::reset().
◆ byteCount()
|
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.
◆ next()
|
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.
Referenced by avro::copy(), and avro::StreamReader::fill().
