bool avro::StreamReader::fill (  )  [inline]

Get as many byes from the underlying stream as possible in a single chunk.

Returns:
true if some data could be obtained. False is no more data is available on the stream.

uint8_t avro::StreamReader::read (  )  [inline]

Read just one byte from the underlying stream.

If there are no more data, throws an exception.

void avro::StreamReader::readBytes ( uint8_t *  b,
size_t  n 
) [inline]

Reads the given number of bytes from the underlying stream.

If there are not that many bytes, throws an exception.

void avro::StreamReader::skipBytes ( size_t  n  )  [inline]

Skips the given number of bytes.

Of there are not so that many bytes, throws an exception.
