## Detailed Description

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

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

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

## Member Function Documentation

### iterator::iterator ( const iterator & other )

Constructs a copy of other.

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

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

See also operator==().

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

Returns the current element.

### iterator 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+=().

### iterator & 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--().

### iterator 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.

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

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

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

### iterator 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 iterator::operator- ( iterator other ) const

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

### iterator & 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++().

### iterator 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.

### iterator & 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 iterator::operator< ( 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 iterator::operator<= ( 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 iterator::operator== ( const iterator & other ) const

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

See also operator!=().

### bool iterator::operator> ( 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 iterator::operator>= ( 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.
