Public Member Functions
	QAssociativeConstIterator (QConstIterator &&it)
QVariant	key () const
	Returns the key this iterator points to.
QVariant	value () const
	Returns the mapped value this iterator points to, or an invalid QVariant if there is no mapped value.
QVariant	operator* () const
	Returns the current item, converted to a QVariant.
QVariantConstPointer	operator-> () const
	Returns the current item, converted to a QVariantConstPointer.
Public Member Functions inherited from QConstIterator< QMetaAssociation >
	QConstIterator (const QIterable< QMetaAssociation > *iterable, void *iterator)
	Creates a QConstIterator to wrap iterator, operating on iterable.
bool	operator== (const QConstIterator &o) const
	Returns true if other points to the same item as this iterator; otherwise returns false.
bool	operator!= (const QConstIterator &o) const
	Returns true if other points to a different item than this iterator; otherwise returns false.
QConstIterator &	operator++ ()
	The prefix {++} operator ({++it}) advances the iterator to the next item in the container and returns an iterator to the new current item.
QConstIterator &	operator-- ()
	The prefix {–} operator ({–it}) makes the preceding item current and returns an iterator to the new current item.
QConstIterator &	operator+= (qsizetype j)
	Advances the iterator by j items.
QConstIterator &	operator-= (qsizetype j)
	Makes the iterator go back by j items.
QConstIterator	operator+ (qsizetype j) const
	Returns an iterator to the item at j positions forward from this iterator.
QConstIterator	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.
QMetaAssociation	metaContainer () const

Member Function Documentation

key()

QVariant QAssociativeConstIterator::key

(

)

const

Returns the key this iterator points to.

Definition at line 54 of file qassociativeiterable.cpp.

operator*()

QVariant QAssociativeConstIterator::operator*

(

)

const

Returns the current item, converted to a QVariant.

The returned value is the mapped value at the current iterator if there is one, or otherwise the key.

Definition at line 78 of file qassociativeiterable.cpp.

operator->()

QVariantConstPointer QAssociativeConstIterator::operator->

(

)

const

Returns the current item, converted to a QVariantConstPointer.

The QVariantConstPointer will resolve to the mapped value at the current iterator if there is one, or otherwise the key.

Definition at line 89 of file qassociativeiterable.cpp.

value()

QVariant QAssociativeConstIterator::value

(

)

const

Returns the mapped value this iterator points to, or an invalid QVariant if there is no mapped value.

Definition at line 66 of file qassociativeiterable.cpp.
