Detailed Description

This class provides easier access to the session's properties.

It uses C++ features used in containers to provide a familiar interface, such as overloading the operator [].

bool RequestHandler::handleRequest(Tufao::HttpServerRequest *request,
                                   Tufao::HttpServerResponse *response,
                                   const QStringList &)
{
    Tufao::Session s(store, *request, *response);
    s["access"] = s["access"]().toInt() + 1;
    response->writeHead(200);
    (*response) << "You have "
                << QByteArray::number(s["access"]().toInt())
                << " access";
    response->end();
    return true;
}

Note: All member functions of this class are inlined and should add the minimum (if any) of overhead.

Constructor & Destructor Documentation

Tufao::Session::Session	(	SessionStore &	store,
		const HttpServerRequest &	request,

Constructs a new Session object.

The object will use store, request and response in every operation and you should ensure these objects aren't destructed before this Session object.
