Here it is in the Vault:
What does 'is_const' for iterators mean?
As the patched doc says, the trait returns true if the result of iterator dereference is constant reference and false otherwise. is_const_iterator< str::list< int >::const_iterator >::value == true is_const_iterator< str::list< int >::iterator >::value == false
The New Iterator concept defines Readable and Writable concept, but I don't know the definition of "constant" iterator. Well, I think 'iterator_reference<ItT>::type' can return a const-qualified type even if 'ItT' is Writable.
I don't see how would it be possible to write to a const. -- Best regards, Andrey mailto:andysem@mail.ru
