Hi all,
is it possible with boost::intrusive::slist to obtain the end() iterator from a value object present in a list? Using s_iterator_to() I can obtain a valid iterator from a value reference but i can't forward iterate from it without knowing the end().
Reading the slist code I found the method slist_iterator::get_container but since is a detail implementation, I prefer not to use it.
In most cases it returns null (a pointer to the container is stored only when dereferencing needs to access some container-stored value-traits), s_iterator_to can't be used when value_traits is stateful, so that function is not going to help you.
I also found that a default construct iterator is almost equivalent to end() for linear slists and should work just fine. For circular slists?
There is no way to obtain the end node from a node in a circular list, as there is no runtime information stored in the ring that marks the end node. Best, Ion
