## Detailed Description

The QWebElementCollection::const_iterator class provides an STL-style const iterator for QWebElementCollection.

QWebElementCollection provides STL style const iterators for fast low-level access to the elements.

QWebElementCollection::const_iterator allows you to iterate over a QWebElementCollection.

## Member Function Documentation

### const_iterator::const_iterator(const const_iterator & other)

Constructs a copy of other.

### bool const_iterator::operator!=(const const_iterator & other) const

Returns true if other points to a different element than this; iterator; otherwise returns false.

See also operator==().

### const QWebElement const_iterator::operator*() const

Returns the current element.

### const_iterator const_iterator::operator+(int j) const

Returns an iterator to the element at j positions forward from this iterator. If j is negative, the iterator goes backward.

See also operator-() and operator+=().

### const_iterator & const_iterator::operator++()

The prefix ++ operator (`++it`) advances the iterator to the next element in the collection and returns an iterator to the new current element.

Calling this function on QWebElementCollection::end() leads to undefined results.

See also operator--().

### const_iterator const_iterator::operator++(int)

This is an overloaded function.

The postfix ++ operator (`it++`) advances the iterator to the next element in the collection and returns an iterator to the previously current element.

Calling this function on QWebElementCollection::end() leads to undefined results.

### const_iterator & const_iterator::operator+=(int j)

Advances the iterator by j elements. If j is negative, the iterator goes backward.

See also operator-=() and operator+().

### const_iterator const_iterator::operator-(int j) const

Returns an iterator to the element at j positiosn backward from this iterator. If j is negative, the iterator goes forward.

See also operator+() and operator-=().

### int const_iterator::operator-(const_iterator other) const

Returns the number of elements between the item point to by other and the element pointed to by this iterator.

### const_iterator & const_iterator::operator--()

The prefix -- operator (`--it`) makes the preceding element current and returns an iterator to the new current element.

Calling this function on QWebElementCollection::begin() leads to undefined results.

See also operator++().

### const_iterator const_iterator::operator--(int)

This is an overloaded function.

The postfix -- operator (`it--`) makes the preceding element current and returns an iterator to the previously current element.

### const_iterator & const_iterator::operator-=(int j)

Makes the iterator go back by j elements. If j is negative, the iterator goes forward.

See also operator+=() and operator-().

### bool const_iterator::operator<(const const_iterator & other) const

Returns true if the element pointed to by this iterator is less than the element pointed to by the other iterator.

### bool const_iterator::operator<=(const const_iterator & other) const

Returns true if the element pointed to by this iterator is less than or equal to the element pointed to by the other iterator.

### bool const_iterator::operator==(const const_iterator & other) const

Returns true if other points to the same item as this iterator; otherwise returns false.

See also operator!=().

### bool const_iterator::operator>(const const_iterator & other) const

Returns true if the element pointed to by this iterator is greater than the element pointed to by the other iterator.

### bool const_iterator::operator>=(const const_iterator & other) const

Returns true if the element pointed to by this iterator is greater than or equal to the element pointed to by the other iterator.
