Make Visitable - GerdHirsch/Cpp-VisitorFrameworkCyclicAcyclic GitHub Wiki
Extend your classes non invasiv with the property "Visitable".
All what you need is a
Repository with your classes and a
Factory<Repository>
to do the following:
Visitables visitables;
NonVisitable nv;
auto pU = std::make_unique<NonVisitable>();
auto pS = std::make_shared<int>(42);
DemoVisitor visitor;
// by Reference
visitables.push_back(Factory::makeVisitable(nv));
// by Value
visitables.push_back(Factory::makeVisitable(NonVisitable()));
visitables.push_back(Factory::makeVisitable(3.14));
// by unique_ptr
visitables.push_back(Factory::makeVisitable(std::move(pU) ));
visitables.push_back(Factory::makeVisitable(std::make_unique<NonVisitable>() ));
// by weak_ptr
visitables.push_back(Factory::makeVisitable(pS));
demoRunVisitor(visitor, visitables);
As you can see, it's possible to visit even build-in types with the framework.
you will find further information in DemoVisitorNonVisitable and in demoRunVisitor
