[Boost-users] using bind with operator new

19 May 2009


      I am trying to use bind to generate ptr_vector list of objects from another 
vector

#include <boost/shared_ptr.hpp>
#include <boost/bind.hpp>

class a
{
};

class b
{
public:
	b(a* val) : _val(val)
	{
	}
private:
	boost::shared_ptr<a> _val;
};


void test()
{
	boost::ptr_vector<a> lsta;
	boost::ptr_vector<b> lstb;

	typedef boost::ptr_vector<b> listofb;

        // create lstb by applying new to each element of lsta and pushing it 
to lstb. Fails. I will appreciate any help with this.
	std::for_each (lsta.begin(), lsta.end,
		
		boost::bind((&listofb::push_back), lstb, 
			boost::bind((&operator new), b, _1)
		);
}
