	genPackage This is factory method that generate data pacakge objects by command. All object should be registered before using this method.
bool	checkCommand (unsigned short cmd) const
	checkCommand This method check command are if registered type or not.
virtual void	initSupportedCommands ()
	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.
QString	toString () const override

	multiVersionPackages return list of the supported multiversions packages.

parsePackage This is main method of all childs classes of an AbstractNode class. This method work on own thread. If you ovveride this method you need to create this than an example:

ParserResult DataBaseNode::parsePackage(PKG::AbstractData *pkg,
                                        const Header& pkgHeader,
                                        const AbstractNodeInfo* sender) {
    auto parentResult = AbstractNode::parsePackage(pkg, sender);
    if (parentResult != ParserResult::NotProcessed) {
        return parentResult;
    }
 
    // you can use parsing without the commandHandler method
    if (MyCommand::command() == pkg->cmd()) {
 
        BaseId requesterId = getSender(sender, &obj);
 
        ...
 
        if (FailCondition) {
            return ParserResult::Error;
        }
 
        ...
 
        return ParserResult::Processed;
 
    }
 
    // 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;
}

Parameters

pkg	This is package with incomming data.
sender	This is sender this pacakge.
pkgHeader	This is header of the incoming packet is used to create a response.

Returns

item of ParserResult. For more information see The ParserResult enum.
