QuasarApp Heart

QuasarApp Heart - it is base backend for C++/Qt projects. This library support work with databases and work with lite network requests.

Futures

This library consists of two levels (AbstractNode level and DataBaseNode level).

Support ssl sockets
Support initialize database
Support work in database

Usage

Create a own package class and override some basic methods.

class MyPackage: public QH::AbstractData
{
public:
    MyPackage();

    // override this method for validation your package class
    bool isValid() const {
        return AbstractData::isValid();
    };                     

    // your data for for server of client
    std::string _data = "";

protected:
    // StreamBase interface override this methods for serialization your package
    QDataStream &fromStream(QDataStream &stream) {
        stream >> _data;
        return stream;
    }
    QDataStream &toStream(QDataStream &stream) const {
        stream << _data;
        return stream;
    }

};

Create your parser api class.

*
* class MyParser: public QH::iParser {
   public:
       MyParser(QH::AbstractNode* parentNode): QH::iParser(parentNode) {
           registerPackageType<MyPackage>();
           data = new BigPackage();
   }

   // iParser interface
   public:

   // override this method for processed received data.
   ParserResult parsePackage(const Package &pkg,
                             const AbstractNodeInfo *sender) {

       auto parentResult = AbstractNode::parsePackage(pkg, sender);
       if (parentResult != ParserResult::NotProcessed) {
           return parentResult;
       }

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

       return ParserResult::NotProcessed;
   }

   bool processMyPackage(const QSharedPointer<MyPackage> &cardrequest,
                         const QH::AbstractNodeInfo *sender, const QH::Header &hdr) {

       BaseId requesterId = getSender(sender, &cardrequest);

       if (!cardrequest.isValid()) {
           badRequest(sender->networkAddress(), hdr);
           return ParserResult::Error;
       }

       cardrequest._data = "responce for client "

       // responce only for servers.
       if (nodeType() == QH::AbstractNode::NodeType::Server)
           sendData(cardrequest, sender->networkAddress(), &pkg.hdr);

       return ParserResult::Processed;
   }

   // This vesion of the parser (any digital value.) .
   int version() const override {return 0;};
   QString parserId() const override {return "MyParser";};

   };

Create a server class and add supported parsers to work with packages.

class TestingServer: public QH::AbstractNode {
Q_OBJECT
public:
    TestingServer() {
        addApiParser<MyParser>();
    }

    QH::AbstractNode::NodeType nodeType() const override {
        return QH::AbstractNode::NodeType::Server;
    }
};

Create a client class and add supported parsers to work with packages.

class TestingClient: public QH::AbstractNode {

public:
    TestingClient() {
        addApiParser<MyParser>();
    }

    QH::AbstractNode::NodeType nodeType() const override {
        return QH::AbstractNode::NodeType::Client;
    }
};
