| Encodes fixed length binary to the current stream. | |
| void | encodeFixed (const std::vector< uint8_t > &bytes) |
| Encodes an Avro data type Fixed. | |
| virtual void | encodeEnum (size_t e)=0 |
| Encodes enum to the current stream. | |
| virtual void | arrayStart ()=0 |
| Indicates that an array of items is being encoded. | |
| virtual void | arrayEnd ()=0 |
| Indicates that the current array of items have ended. | |
| virtual void | mapStart ()=0 |
| Indicates that a map of items is being encoded. | |
| virtual void | mapEnd ()=0 |
| Indicates that the current map of items have ended. | |
| virtual void | setItemCount (size_t count)=0 |
| Indicates that count number of items are to follow in the current array or map. | |
| virtual void | startItem ()=0 |
| Marks a beginning of an item in the current array or map. | |
| virtual void | encodeUnionIndex (size_t e)=0 |
| Encodes a branch of a union. The actual value is to follow. | |
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.
| bytes | Where the data is | |
| len | Number of bytes at bytes. |

| void avro::Encoder::encodeBytes | ( | const std::vector< uint8_t > & | bytes | ) | [inline] |
Encodes aribtray binary data into tthe current stream as Avro "bytes" data type.
| bytes | The data. |
| void avro::Encoder::encodeFixed | ( | const std::vector< uint8_t > & | bytes | ) | [inline] |
Encodes an Avro data type Fixed.
| bytes | The fixed, the length of which is taken as the size of fixed. |
| virtual void avro::Encoder::init | ( | OutputStream & | os | ) | [pure virtual] |

| virtual void avro::Encoder::setItemCount | ( | size_t | count | ) | [pure virtual] |
Indicates that count number of items are to follow in the current array or map.
