Public Member Functions
	QAssociativeIterator (QIterator &&it)

QVariant	key () const
	Returns the key this iterator points to.

QVariantRef< QAssociativeIterator >	value () const
	Returns the mapped value this iterator points to.

QVariantRef< QAssociativeIterator >	operator* () const
	Returns the current item, converted to a QVariantRef.

QVariantPointer< QAssociativeIterator >	operator-> () const
	Returns the current item, converted to a QVariantPointer.

Public Member Functions inherited from QIterator< QMetaAssociation >
	QIterator (QIterable< QMetaAssociation > iterable, void iterator)
	Creates an iterator from an iterable and a pointer to a native iterator.

bool	operator== (const QIterator &o) const
	Returns `true` if other points to the same item as this iterator; otherwise returns `false`.

bool	operator!= (const QIterator &o) const
	Returns `true` if other points to a different item than this iterator; otherwise returns `false`.

QIterator &	operator++ ()
	The prefix {++} operator ({++it}) advances the iterator to the next item in the container and returns an iterator to the new current item.

QIterator	operator++ (int)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.The postfix {++} operator ({it++}) advances the iterator to the next item in the container and returns an iterator to the previously current item.

QIterator &	operator-- ()
	The prefix {–} operator ({–it}) makes the preceding item current and returns an iterator to the new current item.

QIterator	operator-- (int)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.The postfix {–} operator ({it–}) makes the preceding item current and returns an iterator to the previously current item.

QIterator &	operator+= (qsizetype j)
	Advances the iterator by j items.

QIterator &	operator-= (qsizetype j)
	Makes the iterator go back by j items.

QIterator	operator+ (qsizetype j) const
	Returns an iterator to the item at j positions forward from this iterator.

QIterator	operator- (qsizetype j) const
	Returns an iterator to the item at j positions backward from this iterator.

qsizetype	operator- (const QIterator &j) const
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Returns the distance between the two iterators.

Public Member Functions inherited from QBaseIterator< Container >
void *	mutableIterator ()
	Returns a non-const pointer to the internal native iterator.

Member Function Documentation

◆ key()

QT_BEGIN_NAMESPACE QVariant QAssociativeIterator::key ( ) const

Returns the key this iterator points to.

Definition at line 14 of file qassociativeiterable.cpp.

Here is the call graph for this function:

◆ operator*()

QVariantRef< QAssociativeIterator > QAssociativeIterator::operator* ( ) const

Returns the current item, converted to a QVariantRef.

The resulting QVariantRef resolves to the mapped value if there is one, or to the key value if not.

Definition at line 37 of file qassociativeiterable.cpp.

◆ operator->()

QVariantPointer< QAssociativeIterator > QAssociativeIterator::operator-> ( ) const

Returns the current item, converted to a QVariantPointer.

The resulting QVariantPointer resolves to the mapped value if there is one, or to the key value if not.

Definition at line 47 of file qassociativeiterable.cpp.

◆ value()

QVariantRef< QAssociativeIterator > QAssociativeIterator::value ( ) const

Returns the mapped value this iterator points to.

If the container does not provide a mapped value (for example a set), returns an invalid QVariantRef.
