Detailed Description
template<typename Key, typename Val, typename C>
class QFlatMap< Key, Val, C >::const_iterator
The QFlatMap::const_iterator class provides an STL style const iterator for QFlatMap. QFlatMap features both STL style iterators and Java style iterators.
QFlatMap::const_iterator allows you to iterate over a QFlatMap. If you want to modify the QFlatMap as you iterate over it use QFlatMap::iterator instead.
After construction you must initialize the iterator using a method like QFlatMap::constBegin(), QFlatMap::constEnd(), or QFlatMap::find() before you can start iterating.
The following example prints all of the (key, value) pairs stored in the flat map.

Equivalent to std::bidirectional_iterator_tag indicating this iterator is a bidirectional iterator.
Constructor & Destructor Documentation
|
default |
Constructs an uninitialized iterator.
Methods like key(), value(), and operator++() must not be called on an uninitialized iterator. Use operator=() to assign a value to it before using it.
|
inline |
Constructs a copy of iter.
Method Documentation
|
inline |
Returns the current item's key.
- See also
- value()
|
inline |
Returns true if other points to a different item than this iterator, otherwise it returns false.
- See also
- operator==()
|
inline |
|
inline |
Returns an iterator to the item at n positions forward from this iterator. If n is negative the iterator goes backward.
This operation can be slow for large values of n.
- See also
- operator-()
|
inline |
The prefix ++ operator (++i) advances the iterator to the next item in the map and returns an iterator to the new current item.
Calling this method on QFlatMap::end() leads to undefined behavior.
- See also
- operator--()
|
inline |
The postfix ++ operator (i++) advances the iterator to the next item in the map and returns an iterator to the previously current item.
|
inline |
Advances the iterator by n items. If n is negative the iterator goes backward.
This operation can be slow for large values of n.
- See also
- operator-=(), operator+()
|
inline |
Returns an iterator to the item at n positions backward from this iterator. If n is negative the iterator goes forward.
This operation can be slow for large values of n.
- See also
- operator+()
|
inline |
The prefix – operator (–i) makes the preceding item current and returns an iterator pointing to the new current item.
Calling this method on QFlatMap::begin() leads to undefined behavior.
- See also
- operator++()
|
inline |
The postfix – operator (i–) makes the preceding item current and returns an iterator pointing to the previously current item.
|
inline |
Makes the iterator go back by n items. If n is negative the iterator goes forward. This operation can be slow for large values of n.
- See also
- operator+=(), operator-()
|
inline |
Returns a pointer to the current item's value.
- See also
- value()
|
inline |
Returns true if other points to the same item as this iterator, otherwise it returns false.
- See also
- operator!=()
|
inline |
Returns a pair consisting of the key and the value.
|
inline |
Returns the current item's value.
- See also
- key(), operator*()
