Re: [Boost-users] multi_array, resize and default constructable

It is thus not possible providing a default fill element?

The default fill element is the default value of the type. For example, if you have a multi_array of doubles, on array construction (or resize) all new elements will be 0.0. You cannot change this value without changing the default value of the underlying type. Johann

I understand that, built in types are also defined for default construction. However I had a need here to override that default. Looking at the vector::resize(), it offers an overload function for specifying the fill element. The case I needed was soemthing likea std::pair, where the the default handle is -1 (i.e. std::pair default(-1, ""));. Of course this can be solved by promoting this to a full blown struct with default ctor, but I donot like to introduce extra structures for just bundling data.
