hmm can you give a small example of what you mean.. calling clone_allocators' allocate clone On Nov 28, 2007 5:38 AM, Thorsten Ottosen <thorsten.ottosen@dezide.com> wrote:

is it possible to use stl set_unions with ptr_container or do I have to hand roll my own. if yes what inserter should i use or how would i use two containers having pointer of int ptr_vector<int> a1; ptr_vector<int> a2;

have a1 union a2 and store in a3.

Should be possible, but you need a different out-put iterator compared to e.g. std::back_inserter( a_normal_container ).

Specifically, you need to call a3's clone_allocators' allocate_clone() in the call to push_back().

hmm yeah i want to be able to store them in ptr_vector<int> a3. Since this doesn't work.. you think their would be future work around to support integeration with stl algorithms. On Nov 28, 2007 2:44 PM, Thorsten Ottosen <thorsten.ottosen@dezide.com> wrote:

Calling new_clone() is probably sufficient for most purposes.

I'm curious as to why one would ever want a ptr_vector of int's? Or is this just used in this example? Jeff Flinn
