Inheritance diagram for QgsCachedFeatureIterator:

Public Member Functions
	QgsCachedFeatureIterator (QgsVectorLayerCache *vlCache, const QgsFeatureRequest &featureRequest)
	This constructor creates a feature iterator, that delivers all cached features. More...

bool	close () override
	Close this iterator. More...

bool	rewind () override
	Rewind to the beginning of the iterator. More...

Public Member Functions inherited from QgsAbstractFeatureIterator
	QgsAbstractFeatureIterator (const QgsFeatureRequest &request)
	base class constructor - stores the iteration parameters More...

virtual	~QgsAbstractFeatureIterator ()=default
	destructor makes sure that the iterator is closed properly More...

CompileStatus	compileStatus () const
	Returns the status of expression compilation for filter expression requests. More...

virtual bool	isValid () const
	Returns if this iterator is valid. More...

virtual bool	nextFeature (QgsFeature &f)
	fetch next feature, return true on success More...

virtual void	setInterruptionChecker (QgsFeedback *interruptionChecker)
	Attach an object that can be queried regularly by the iterator to check if it must stopped. More...

Protected Member Functions
bool	fetchFeature (QgsFeature &f) override
	Implementation for fetching a feature. More...

bool	nextFeatureFilterFids (QgsFeature &f) override
	We have a local special iterator for FilterFids, no need to run the generic. More...

Protected Member Functions inherited from QgsAbstractFeatureIterator
void	deref ()
	Remove reference, delete if refs == 0. More...

QgsRectangle	filterRectToSourceCrs (const QgsCoordinateTransform &transform) const
	Returns a rectangle representing the original request's QgsFeatureRequest::filterRect(). More...

void	geometryToDestinationCrs (QgsFeature &feature, const QgsCoordinateTransform &transform) const
	Transforms feature's geometry according to the specified coordinate transform. More...

virtual bool	nextFeatureFilterExpression (QgsFeature &f)
	By default, the iterator will fetch all features and check if the feature matches the expression. More...

virtual bool	prepareSimplification (const QgsSimplifyMethod &simplifyMethod)
	Setup the simplification of geometries to fetch using the specified simplify method. More...

void	ref ()
	Add reference. More...

Additional Inherited Members
Public Types inherited from QgsAbstractFeatureIterator
enum	CompileStatus { NoCompilation, PartiallyCompiled, Compiled }
	Status of expression compilation for filter expression requests. More...

Protected Attributes inherited from QgsAbstractFeatureIterator
bool	mClosed = false
	Set to true, as soon as the iterator is closed. More...

CompileStatus	mCompileStatus = NoCompilation
	Status of compilation of filter expression. More...

long	mFetchedCount = 0
	Number of features already fetched by iterator. More...

QgsFeatureRequest	mRequest
	A copy of the feature request. More...

bool	mValid = true
	An invalid state of a feature iterator indicates that there was a problem with even getting it up and running. More...

bool	mZombie = false
	A feature iterator may be closed already but still be serving features from the cache. More...

int	refs = 0
	reference counting (to allow seamless copying of QgsFeatureIterator instances) TODO QGIS3: make this private More...
