deserializePayload method

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

  // field name
  var nameSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var nameDData = List.filled(nameSSize, 0);
  for (var i = 0; i < nameSSize; i++) {
    nameDData[i] = byteData.getUint8(byteOffset++);
  }
  var nameDecoded = utf8.decode(nameDData);
  builder.name = nameDecoded;
  // field params
  var paramsMMsgsNumber = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  builder.params = [];
  for (var i = 0; i < paramsMMsgsNumber; i++) {
    var paramsSId = byteData.getUint16(byteOffset, endianness);
    byteOffset += 2;
    if (paramsSId != imc.ImcId.nullId) {
      var pMsgBuilder = imc.messagesBuilders[
              imc.idsToMessages[paramsSId] ?? imc.ImcId.nullId.toString()]
          ?.call()
          .newInstance(builder);
      var pMsgSerializer = imc.messagesSerializers[
              imc.idsToMessages[paramsSId] ?? imc.ImcId.nullId.toString()]
          ?.call();
      if (pMsgBuilder != null && pMsgSerializer != null) {
        var mPSize = pMsgSerializer.deserializePayload(
            pMsgBuilder, byteData, endianness, byteOffset);
        byteOffset += mPSize;
        builder.params.add(pMsgBuilder.build() as imc.EntityParameter);
      }
    }
  }

  return byteOffset - offset;
