deserializePayload method

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

  // field msgs
  var msgsMMsgsNumber = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  builder.msgs = [];
  for (var i = 0; i < msgsMMsgsNumber; i++) {
    var msgsSId = byteData.getUint16(byteOffset, endianness);
    byteOffset += 2;
    if (msgsSId != imc.ImcId.nullId) {
      var pMsgBuilder = imc.messagesBuilders[
              imc.idsToMessages[msgsSId] ?? imc.ImcId.nullId.toString()]
          ?.call()
          .newInstance(builder);
      var pMsgSerializer = imc.messagesSerializers[
              imc.idsToMessages[msgsSId] ?? imc.ImcId.nullId.toString()]
          ?.call();
      if (pMsgBuilder != null && pMsgSerializer != null) {
        var mPSize = pMsgSerializer.deserializePayload(
            pMsgBuilder, byteData, endianness, byteOffset);
        byteOffset += mPSize;
        builder.msgs.add(pMsgBuilder.build() as imc.ImcMessage);
      }
    }
  }

  return byteOffset - offset;
