[Boost-users] A doubt in Boost Format

Hi, We are using Boost format in our project. We want to replace the normal allocator with a special allocator and we don't want any allocation be made with normal new. I was looking at the Boost fusion reference. format_class.hpp The class accepts a allocator and indeed uses it to instantiate the std::string inside. But there are two vectors inside - std::vector<format_item_t> items_; // each '%..' directive leads to a format_item std::vector<bool> bound_; // stores which arguments were bound. size() == 0 || num_args I am seeing that the vectors are not using the allocators. Is this the intended behavior? Is it right, to try to make an application not to use the normal new/delete completely? Thanks, Gokul.
