I am sorry that I did not figure out the whole intention. Beside calling member function, I hope to delete the object immediately. I wrote the code at first time: std::for_each( items.rbegin(), items.rend(), (_1->*&DiscardableItem::Discard, bind(delete_ptr(), _1)) ); after for_each, objects deleted, but Discard function did not been called. If using Bind can do the same thing, please tell me. thanks! 2009/3/23 Alex MDC <alex.mdc@gmail.com>
But DiscardableItem::Discard does not be called. How can I make it work?
thanks! I think lambda can solve this problem easily.
You don't need boost::lambda here, you can easily solve this with boost::bind
std::for_each( items.rbegin(), items.rend(), boost::bind(&DiscardableItem::Discard, _1) );
If you *want* to use boost::lambda I'm sure someone else will help :)
