reverse_iterator();
explicit reverse_iterator (Iterator x)
template <class U>
reverse_iterator (const reverse_iterator<U>& u);
Constructs reverse_iterator object
Constructs a reverse iterator object.
The first version (the default constructor) constructs an iterator pointing to no object.
The second version constructs a reverse_iterator from some original iterator. The behavior of the constructed object will be the same as the original, except that its directional interpretation will be the opposed one.
The third version constructs a reverse_iterator from some other reverse iterator. The constructed object will keep the same direction as the reverse iterator passed as constructor argument.
Parameters
- x
- An iterator object.
Iterator is reverse_iterator's template parameter (the type of the base iterator).
- u
- A reverse_iterator object.
