[Boost-users] [Variant] Sorting data out of a vector of variant

14 Oct 2009

      Hi all!

I have some class with a member which is a vector of boost.variant, i.e.

class Example
{
public:
    std::vector<variant<typeA, typeB, typeC> > content;
}

I want to add three members to my class that are vectors of pointers to
the specific content items

class Example
{
public:
    std::vector<variant<typeA, typeB, typeC> > content;

    std::vector<typeA> *contentA;
    std::vector<typeB> *contentB;
    std::vector<typeC> *contentC;
}

Now the question: how can I iterate through the vector content whilst
adding its items to the other 3 vectors depending on their type? I know
there has to be some way using the apply_visitor functor, but I just
don't see how exactly...

Thanks for your help!

Best regards,
Oli
