serializePayload method

@override int serializePayload(PlanVariable? message, ByteData byteData, int offset)

Call to serialize only the payload, no header, returns a int with a serialized size

Implementation

@override
int serializePayload(
    imc.PlanVariable? message, ByteData byteData, int offset) {
  if (message == null) return 0;

  var byteOffset = offset;

  // field name
  var nameEncoded = utf8.encode(message.name);
  var nameSSize = nameEncoded.length;
  byteData.setUint16(byteOffset, nameSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in nameEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field value
  var valueEncoded = utf8.encode(message.value);
  var valueSSize = valueEncoded.length;
  byteData.setUint16(byteOffset, valueSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in valueEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field type
  byteData.setUint8(byteOffset, message.type.value);
  byteOffset += 1;
  // field access
  byteData.setUint8(byteOffset, message.access.value);
  byteOffset += 1;

  return byteOffset - offset;
