A server filter to apply a dimension filter to a request.
Abstract interface for use by classes that filter the features or attributes of a layer.
virtual void filterFeatures(const QgsVectorLayer *layer, QgsFeatureRequest &featureRequest) const =0
Add additional filters to the feature request to further restrict the features returned by the reques...
virtual QStringList layerAttributes(const QgsVectorLayer *layer, const QStringList &attributes) const =0
Returns the list of visible attribute names from a list of attributes names for the given layer.
virtual QgsFeatureFilterProvider * clone() const =0
Create a clone of the feature filter provider.
This class wraps a request for features to a vector layer (or directly its vector data provider).
Represents a vector layer which manages a vector based data sets.
