You can use qmlRegisterType to pass the Info of the C++ class to QML 
like this in the cpp:

#include "bloomfilters.h"

int main(int argc, char *argv[])
{
   // Get App and QML-View objects
   QScopedPointer<QGuiApplication> app(SailfishApp::application(argc, 
argv));
   QScopedPointer<QQuickView> view(SailfishApp::createView());

   // Register Bloomfilter Class
   qmlRegisterType<Bloomfilter, 1>("harbour.myapp.Bloomfilter", 1, 0, 
"Bloomfilter");

   // Prepare the QML
   view->setSource(SailfishApp::pathTo("qml/bloomfilter.qml"));
   view->show();

   // Run the app
   return app->exec();
}

Afterwards you can create a Bloomfilter-Object in QML:

Bloomfilter {
   id: bloom
}

and use the methods with

bloom.insertElement("myelement")

I hope this helps.
