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

29 Nov 2007

      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.

hmm can you give a small example of what you mean.. calling
clone_allocators' allocate clone
Calling new_clone() is probably sufficient for most purposes.

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().
