Returns a reference to the object's hash of layers to original subsetString filters.
QgsOWSServerFilterRestorer(const QgsOWSServerFilterRestorer &rh)=delete
QgsOWSServerFilterRestorer cannot be copied.
~QgsOWSServerFilterRestorer()
Destructor. When object is destroyed all original layer filters will be restored.
static void applyAccessControlLayerFilters(const QgsAccessControl *accessControl, QgsMapLayer *mapLayer, QHash< QgsMapLayer *, QString > &originalLayerFilters)
Apply filter from AccessControl.
QgsOWSServerFilterRestorer & operator=(const QgsOWSServerFilterRestorer &rh)=delete
QgsOWSServerFilterRestorer cannot be copied.
QgsOWSServerFilterRestorer()=default
Default constructor for QgsOWSServerFilterRestorer.
static void applyAccessControlLayerFilters(const QgsAccessControl *accessControl, QgsMapLayer *mapLayer)
Applies filters from access control on layer.
