Re: [Boost-users] boost-users [pointer containers] stl set_unions

chun ping wang skrev:

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(). -Thorsten
