deserializePayload method

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

  // field command
  builder.command =
      imc.EmergencyControlEnumCommand(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field plan
  var planSId = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  if (planSId == imc.ImcId.nullId) {
    builder.plan = null;
  } else {
    var pMsgBuilder = imc.messagesBuilders[
            imc.idsToMessages[planSId] ?? imc.ImcId.nullId.toString()]
        ?.call()
        .newInstance(builder);
    var pMsgSerializer = imc.messagesSerializers[
            imc.idsToMessages[planSId] ?? imc.ImcId.nullId.toString()]
        ?.call();
    if (pMsgBuilder != null && pMsgSerializer != null) {
      var mPSize = pMsgSerializer.deserializePayload(
          pMsgBuilder, byteData, endianness, byteOffset);
      byteOffset += mPSize;
      builder.plan = pMsgBuilder.build() as imc.PlanSpecification?;
    }
  }

  return byteOffset - offset;
}
