You want comp.lang.c++.moderated, for example.

Is there a way to determine if a template parameters is of type boost::shared_ptr at compile time?

I would like to do something like:

template<class A> void doSomething( const A& a) { // if "a" is of type boost::shared_ptr<SomeType> a->someMethod(); // else a.someMethod(); }

You don't do that at runtime, of course. I'd dispatch to a struct using partial specialization to get the shared_ptr versus other types behaviors. _____ Rob Stewart robert.stewart@sig.com Software Engineer, Core Software using std::disclaimer; Susquehanna International Group, LLP http://www.sig.com IMPORTANT: The information contained in this email and/or its attachments is confidential.

Is this possible at all?

Yes it is: template <typename A> void doSomething(A const& a) { a.someMethod(); } template <typename A> void doSomething(shared_ptr<A> a) { a->someMethod(); }
