Member Function Documentation

const_iterator::const_iterator(const const_iterator &other)

Creates a copy of other.

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

Assigns other to this.

const_iterator::~const_iterator()

Destroys the QSequentialIterable::const_iterator.

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

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

See also operator==().

const QVariant const_iterator::operator*() const

Returns the current item, converted to a QVariant.

const_iterator const_iterator::operator+(int j) const

Returns an iterator to the item at j positions forward from this iterator.

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

const_iterator &const_iterator::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 QSequentialIterable::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 item in the container and returns an iterator to the previously current item.

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

Advances the iterator by j items.

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

const_iterator const_iterator::operator-(int j) const

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 canReverseIterate().

const_iterator &const_iterator::operator--()

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

Calling this function on QSequentialIterable::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 canReverseIterate().

const_iterator const_iterator::operator--(int)

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 canReverseIterate().

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

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 canReverseIterate().

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!=().
