See also QIterator and QIterable.
Creates a QConstIterator to wrap iterator, operating on iterable.
Returns true if other points to a different item than this iterator; otherwise returns false.
See also operator==().
Returns an iterator to the item at j positions forward from this iterator.
See also operator-() and operator+=().
The prefix ++ operator (++it) advances the iterator to the next item in the container and returns an iterator to the new current item.
Calling this function on QIterable<Container>::end() leads to undefined results.
See also operator--().
This is an overloaded function.
The postfix ++ operator (it++) advances the iterator to the next item in the container and returns an iterator to the previously current item.
Advances the iterator by j items.
See also operator-=() and operator+().
Returns an iterator to the item at j positions backward from this iterator.
If the container in the QVariant does not support bi-directional iteration, calling this function leads to undefined results.
See also operator+(), operator-=(), and QIterable::canReverseIterate().
Returns the distance between the two iterators.
See also operator+(), operator-=(), and QIterable::canReverseIterate().
The prefix -- operator (--it) makes the preceding item current and returns an iterator to the new current item.
Calling this function on QIterable<Container>::begin() leads to undefined results.
If the container in the QVariant does not support bi-directional iteration, calling this function leads to undefined results.
See also operator++() and QIterable::canReverseIterate().
This is an overloaded function.
The postfix -- operator (it--) makes the preceding item current and returns an iterator to the previously current item.
If the container in the QVariant does not support bi-directional iteration, calling this function leads to undefined results.
See also QIterable::canReverseIterate().
Makes the iterator go back by j items.
If the container in the QVariant does not support bi-directional iteration, calling this function leads to undefined results.
See also operator+=(), operator-(), and QIterable::canReverseIterate().
Returns true if other points to the same item as this iterator; otherwise returns false.
See also operator!=().
