deserializePayload method

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

  // field timeline
  var timelineSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var timelineDData = List.filled(timelineSSize, 0);
  for (var i = 0; i < timelineSSize; i++) {
    timelineDData[i] = byteData.getUint8(byteOffset++);
  }
  var timelineDecoded = utf8.decode(timelineDData);
  builder.timeline = timelineDecoded;
  // field predicate
  var predicateSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var predicateDData = List.filled(predicateSSize, 0);
  for (var i = 0; i < predicateSSize; i++) {
    predicateDData[i] = byteData.getUint8(byteOffset++);
  }
  var predicateDecoded = utf8.decode(predicateDData);
  builder.predicate = predicateDecoded;
  // field attributes
  var attributesMMsgsNumber = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  builder.attributes = [];
  for (var i = 0; i < attributesMMsgsNumber; i++) {
    var attributesSId = byteData.getUint16(byteOffset, endianness);
    byteOffset += 2;
    if (attributesSId != imc.ImcId.nullId) {
      var pMsgBuilder = imc.messagesBuilders[
              imc.idsToMessages[attributesSId] ?? imc.ImcId.nullId.toString()]
          ?.call()
          .newInstance(builder);
      var pMsgSerializer = imc.messagesSerializers[
              imc.idsToMessages[attributesSId] ?? imc.ImcId.nullId.toString()]
          ?.call();
      if (pMsgBuilder != null && pMsgSerializer != null) {
        var mPSize = pMsgSerializer.deserializePayload(
            pMsgBuilder, byteData, endianness, byteOffset);
        byteOffset += mPSize;
        builder.attributes.add(pMsgBuilder.build() as imc.TrexAttribute);
