deserializePayload method

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

  // field groupName
  var groupNameSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var groupNameDData = List.filled(groupNameSSize, 0);
  for (var i = 0; i < groupNameSSize; i++) {
    groupNameDData[i] = byteData.getUint8(byteOffset++);
  }
  var groupNameDecoded = utf8.decode(groupNameDData);
  builder.groupName = groupNameDecoded;
  // field action
  builder.action = imc.SystemGroupEnumAction(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field groupList
  var groupListSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var groupListDData = List.filled(groupListSSize, 0);
  for (var i = 0; i < groupListSSize; i++) {
    groupListDData[i] = byteData.getUint8(byteOffset++);
  }
  var groupListDecoded = utf8.decode(groupListDData);
  builder.groupList = groupListDecoded;

  return byteOffset - offset;
}
