[Boost-users] [ptr_vector] vector<ptr_vector < T > >

Hi!

Can anyone tell me why std::vector < boost::ptr_vector < T > > can not be 
reserved and resized I can not push_back anything inside vector, due to 
compile errors?

I am using ptr_vector for storing copyable, but nonassignable objects of type 
T - in fact objects contains mainly const elements.

Regards.

#include <iostream>
#include <vector>
#include <boost/ptr_container/ptr_vector.hpp>

class Foo
{
public:
    Foo ( int const i, int const & j )
    :i_(i), j_(j)
    {}
    
    Foo ( Foo const & f )
    : i_(f.i_), j_(f.j_)
    {}

private:
    int const i_;
    int const & j_;
    void operator= ( Foo const & f );
};

int main()
{
    using namespace std;
    using namespace boost;

    int k = 10;
    ptr_vector<Foo> g;

    g.push_back ( new Foo(1,k) );
    
    vector<ptr_vector<Foo> > d;
    //d.push_back ( g ); <-- Errors
    //d.resize(5)
    //d.reserve(5)
}
