Member Function Documentation

◆ clone()

QgsDimensionFilter * QgsDimensionFilter::clone ( ) const
overridevirtual

Create a clone of the feature filter provider.

Returns
a new clone

Implements QgsFeatureFilterProvider.

Definition at line 41 of file qgsdimensionfilter.cpp.

◆ filterFeatures()

void QgsDimensionFilter::filterFeatures ( const QgsVectorLayer layer,
QgsFeatureRequest featureRequest 
) const
overridevirtual

Add additional filters to the feature request to further restrict the features returned by the request.

Derived classes must implement this method.

Parameters
layerthe layer to filter
featureRequestthe feature request to update

Implements QgsFeatureFilterProvider.

Definition at line 27 of file qgsdimensionfilter.cpp.

◆ layerAttributes()

QStringList QgsDimensionFilter::layerAttributes ( const QgsVectorLayer layer,
const QStringList &  attributes 
) const
overridevirtual

Returns the list of visible attribute names from a list of attributes names for the given layer.

Since
QGIS 3.18

Implements QgsFeatureFilterProvider.
