Member Function Documentation

const_iterator::const_iterator()

Constructs an uninitialized iterator.

Functions like operator*() and operator++() should not be called on an uninitialized iterartor. Use operator=() to assign a value to it before using it.

See also QFuture::constBegin() and QFuture::constEnd().

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 result than this iterator; otherwise returns false.

See also operator==().

const T &const_iterator::operator*() const

Returns the current result.

const_iterator const_iterator::operator+(int j) const

Returns an iterator to the results 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 result in the future and returns an iterator to the new current result.

Calling this function on QFuture<T>::constEnd() 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 result in the future and returns an iterator to the previously current result.

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

Advances the iterator by j results. (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 result at j positions backward from this iterator. (If j is negative, the iterator goes forward.)

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

const_iterator &const_iterator::operator--()

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

Calling this function on QFuture<T>::constBegin() 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 result current and returns an iterator to the previously current result.

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

Makes the iterator go back by j results. (If j is negative, the iterator goes forward.)

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

const T *const_iterator::operator->() const

Returns a pointer to the current result.

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

Assigns other to this iterator.

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

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

See also operator!=().
