Member Function Documentation
FeatureIterator::FeatureIterator ()
Default Constructor. Create an empty FeatureIterator instance.
FeatureIterator::FeatureIterator (const Esri::ArcGISRuntime::FeatureIterator &other)
Copy constructor from other FeatureIterator.
FeatureIterator::FeatureIterator (Esri::ArcGISRuntime::FeatureIterator &&other)
Move constructor from other FeatureIterator.
FeatureIterator::~FeatureIterator ()
Destructor
QList<Esri::ArcGISRuntime::Feature *> FeatureIterator::features(QObject *parent = nullptr) const
Returns all features in the iterator at once as a list of Feature objects, with an optional parent.
All features in this iterator are returned in the list, regardless of whether any features were already accessed through this iterator. After this call, this FeatureIterator will point past the last feature in the iterator. To start over reading features from the beginning of this iterator, call reset.
The parent of the Feature objects in the list will be the specified parent object. If no parent object is specified, the creator of the returned FeatureIterator (either an instance of FeatureLayer or FeatureQueryResult) will be the parent.
bool FeatureIterator::hasNext () const
Returns true
if there is another feature available.
bool FeatureIterator::isEmpty () const
Returns true
if this FeatureIterator is empty.
Esri::ArcGISRuntime::Feature *FeatureIterator::next(QObject *parent = nullptr) const
Returns the next feature providing an optional parent.
If no parent is specified, the creator of the FeatureIterator (either an instance of FeatureLayer or FeatureQueryResult) takes ownership of the returned feature.
void FeatureIterator::reset()
Points the iterator back to the front.
Esri::ArcGISRuntime::FeatureIterator &FeatureIterator::operator=(const Esri::ArcGISRuntime::FeatureIterator &other)
Assignment operator from other FeatureIterator.
Esri::ArcGISRuntime::FeatureIterator &FeatureIterator::operator=(Esri::ArcGISRuntime::FeatureIterator &&other)
Move operator from other FeatureIterator.
