Re: [Boost-users] [variant] not copy-constructable

From: Felipe Magno de Almeida [mailto:felipe.m.almeida@gmail.com]

What I wanted is a vector of variant and I dont want object1 and object2 to be copied because it is expensive. But Im not figuring out how to do this... tried boost::ref either with no success... :/

Boost.Smart_ptr (http://www.boost.org/libs/smart_ptr/smart_ptr.htm) can help: use boost::shared_ptr, which is a reference-counted smart pointer. typedef boost::variant variant_type; std::vector > vec; boost::shared_ptr v(new variant_type(object1())); vec.push_back(v); // No copying of the variant Bjorn Karlsson
