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

layer	the layer to filter
featureRequest	the 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.
