class QgsFeaturePool : QgsFeatureSink /Abstract/
{
%Docstring(signature="appended")
A feature pool is based on a vector layer and caches features.
.. note::
This class is a technology preview and unstable API.
.. versionadded:: 3.4
%End
%TypeHeaderCode
#include "qgsfeaturepool.h"
%End
public:
QgsFeaturePool( QgsVectorLayer *layer );
%Docstring
Creates a new feature pool for ``layer``.
%End
virtual ~QgsFeaturePool();
bool getFeature( QgsFeatureId id, QgsFeature &feature );
%Docstring
Retrieves the feature with the specified ``id`` into ``feature``.
It will be retrieved from the cache or from the underlying feature source if unavailable.
If the feature is neither available from the cache nor from the source it will return ``False``.
%End
virtual void updateFeature( QgsFeature &feature ) = 0;
%Docstring
Updates a feature in this pool.
Implementations will update the feature on the layer or on the data provider.
%End
virtual void deleteFeature( QgsFeatureId fid ) = 0;
%Docstring
Removes a feature from this pool.
Implementations will remove the feature from the layer or from the data provider.
%End
QgsVectorLayer *layer() const;
%Docstring
Gets a pointer to the underlying layer.
May return a ````None```` if the layer has been deleted.
This must only be called from the main thread.
%End
QString layerId() const;
%Docstring
The layer id of the layer.
%End
QgsWkbTypes::GeometryType geometryType() const;
%Docstring
The geometry type of this layer.
%End
QgsCoordinateReferenceSystem crs() const;
%Docstring
The coordinate reference system of this layer.
%End
QString layerName() const;
%Docstring
Returns the name of the layer.
Should be preferred over :py:func:`~QgsFeaturePool.layer`.name() because it can directly be run on
the background thread.
%End
protected:
void insertFeature( const QgsFeature &feature, bool skipLock = false );
%Docstring
Inserts a feature into the cache and the spatial index.
To be used by implementations of ``addFeature``.
%End
void refreshCache( const QgsFeature &feature );
%Docstring
Changes a feature in the cache and the spatial index.
To be used by implementations of ``updateFeature``.
%End
void removeFeature( const QgsFeatureId featureId );
%Docstring
Removes a feature from the cache and the spatial index.
To be used by implementations of ``deleteFeature``.
%End
