	initSupportedCommands This method will be invoked before add a parser into parser's storage. Use this method to register your command for this parser object. By default, this method does nothing, You still can register your command in the class constructor. But if you use inheritance between your APIs versions to you must use this method, because your constructors both all your commands, this broken API selector of your node.

    // Or with the commandHandler method
 
    auto result = commandHandler<MyPackage>(this, &MyClass::processMyPackage, pkg, sender, pkgHeader);
    if (result != QH::ParserResult::NotProcessed) {
        return result;
    }
 
    return ParserResult::NotProcessed;
}
