void resolveFilterFeatures(const QList< QgsMapLayer * > &layers)
Resolve features' filter of layers The method fetch filter's expressions returned from access control...
void registerAccessControl(QgsAccessControlFilter *accessControl, int priority=0)
Register an access control filter.
void unresolveFilterFeatures()

QgsAccessControl()
Constructor.
QString extraSubsetString(const QgsVectorLayer *layer) const
Returns an additional subset string (typically SQL) filter.
Abstract interface for use by classes that filter the features or attributes of a layer.
This class wraps a request for features to a vector layer (or directly its vector data provider).
QgsFeatureRequest & combineFilterExpression(const QString &expression)
Modifies the existing filter expression to add an additional expression filter.
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Base class for all map layer types.
Represents a vector layer which manages a vector based data sets.
