class QgsFeaturePool : QgsFeatureSink /Abstract/
{
%Docstring
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, QgsFeedback *feedback = 0 );
%Docstring
Retrieves the feature with the specified ``id`` into ``feature``.
It will be retrieved from the cache or from the underlying layer if unavailable.
If the feature is neither available from the cache nor from the layer it will return false.
If ``feedback`` is specified, the call may return if the feedback is canceled.
%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

  protected:

    void insertFeature( const QgsFeature &feature );
%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``.
