Detailed Description

The abstract base class for all Avro encoders.

The implementations differ in the method of encoding (binary vresus JSON) or in capabilities such as ability to verify the order of invocation of different functions.

virtual void avro::Encoder::encodeBytes ( const uint8_t *  bytes,
size_t  len 
) [pure virtual]

Encodes aribtray binary data into tthe current stream as Avro "bytes" data type.

Parameters:
bytes Where the data is
len Number of bytes at bytes.

Referenced by avro::codec_traits< std::vector< uint8_t > >::encode(), and encodeBytes().

void avro::Encoder::encodeBytes ( const std::vector< uint8_t > &  bytes  )  [inline]

Encodes aribtray binary data into tthe current stream as Avro "bytes" data type.

Parameters:
bytes The data.

References encodeBytes().

void avro::Encoder::encodeFixed ( const std::vector< uint8_t > &  bytes  )  [inline]

Encodes an Avro data type Fixed.

Parameters:
bytes The fixed, the length of which is taken as the size of fixed.
