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-- ()
	The prefix {–} operator ({–it}) makes the preceding item current and returns an iterator to the new 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.
Public Member Functions inherited from QBaseIterator< QMetaAssociation >
void *	mutableIterator ()
	Returns a non-const pointer to the internal native iterator.
const void *	constIterator () const
	Returns a const pointer to the internal native iterator.

key_type

using QAssociativeIterator::key_type = QVariant

mapped_type

using QAssociativeIterator::mapped_type = QVariant

Member Function Documentation

key()

QT_BEGIN_NAMESPACE QVariant QAssociativeIterator::key

(

)

const

Returns the key this iterator points to.

Definition at line 13 of file qassociativeiterable.cpp.

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 36 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 46 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.
