23. def generateAvroSingleObjectEncoded(avroPayload: Array[Byte], schema: Schema, endianness: ByteOrder, getId: (Schema) ⇒ Long): Array[Byte]

    

    Create an array that creates a Single-Object encoded byte array.

    Create an array that creates a Single-Object encoded byte array. By specifications the encoded array is obtained concatenating the V1_HEADER, the schema id and the avro-encoded payload.
