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.
