A synonym for std::random_access_iterator_tag indicating this iterator is a random access iterator.

Member Function Documentation

[constexpr noexcept] ConstIterator::ConstIterator()

Constructs an uninitialized iterator.

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

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

[constexpr noexcept] ConstIterator::ConstIterator(const QCborArray::ConstIterator &other)

Constructs a copy of other.

QCborValueConstRef ConstIterator::operator*() const

Returns the current item.

QCborArray::ConstIterator ConstIterator::operator+(qsizetype j) const

Returns an iterator to the item at a position j steps forward from this iterator. If j is negative, the iterator goes backward.

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

QCborArray::ConstIterator &ConstIterator::operator++()

The prefix ++ operator, ++it, advances the iterator to the next item in the array and returns this iterator.

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

See also operator--().

QCborArray::ConstIterator ConstIterator::operator++(int)

This is an overloaded function.

The postfix ++ operator, it++, advances the iterator to the next item in the array and returns an iterator to the previously current item.

QCborArray::ConstIterator &ConstIterator::operator+=(qsizetype j)

Advances the iterator by j positions. If j is negative, the iterator goes backward. Returns a reference to this iterator.

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

qsizetype ConstIterator::operator-(QCborArray::ConstIterator other) const

Returns the offset of this iterator relative to other.

QCborArray::ConstIterator ConstIterator::operator-(qsizetype j) const

Returns an iterator to the item at a position j steps backward from this iterator. If j is negative, the iterator goes forward.

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

QCborArray::ConstIterator &ConstIterator::operator--()

The prefix -- operator, --it, makes the preceding item current and returns this iterator.

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

See also operator++().

QCborArray::ConstIterator ConstIterator::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.

QCborArray::ConstIterator &ConstIterator::operator-=(qsizetype j)

Makes the iterator go back by j positions. If j is negative, the iterator goes forward. Returns a reference to this iterator.

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

const QCborValueConstRef *ConstIterator::operator->() const

Returns a pointer to the current item.

QCborArray::ConstIterator &ConstIterator::operator=(const QCborArray::ConstIterator &other)

Makes this iterator a copy of other and returns a reference to this iterator.

QCborValueConstRef ConstIterator::operator[](qsizetype _j_) const

Returns the item at a position j steps forward from the item pointed to by this iterator.

This function is provided to make QCborArray iterators behave like C++ pointers.
