Probably yes if someone implements this for vector and deque first. ----- Original Message ---- From: Thorsten Ottosen <thorsten.ottosen@dezide.com> To: Jan Gaspar <jano_gaspar@yahoo.com> Cc: "boost@lists.boost.org" <boost@lists.boost.org> Sent: Monday, 16 June, 2008 4:33:25 PM Subject: [circular_buffer] encapsulation problems Hi Jan, Have you ever seen http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2007/n2212.html ? I'm implementing some simple map data-struture as a wrapper around boost::circular_buffer<boost::optional<Pod>>. In my copy-constructor I want to memcpy into a newly created circular_buffer of the correct size, but that is not really possible. In n2212 I outline a solution to this problem. Would you consider to implement them? I think the functions will also make circular_buffer more efficient for use in MPI and Asio. -Thorsten __________________________________________________________ Sent from Yahoo! Mail.
