deserializePayload method

@override int deserializePayload(NeptusBlobBuilder builder, ByteData byteData, Endian endianness, int offset,)

Call to deserialize only the payload, no header. The Builder is to allow passing the message to build into. returns a int with a serialized size

Implementation

@override
int deserializePayload(imc.NeptusBlobBuilder builder, ByteData byteData,
    Endian endianness, int offset) {
  var byteOffset = offset;

  // field contentType
  var contentTypeSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var contentTypeDData = List.filled(contentTypeSSize, 0);
  for (var i = 0; i < contentTypeSSize; i++) {
    contentTypeDData[i] = byteData.getUint8(byteOffset++);
  }
  var contentTypeDecoded = utf8.decode(contentTypeDData);
  builder.contentType = contentTypeDecoded;
  // field content
  var contentSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var contentDData = List.filled(contentSSize, 0);
  for (var i = 0; i < contentSSize; i++) {
    contentDData[i] = byteData.getUint8(byteOffset++);
  }
  builder.content = contentDData;

  return byteOffset - offset;
}
