Class defining access control interface for QGIS Server plugins.
A helper class that centralizes restrictions given by all the access control filter plugins.
~QgsAccessControl() override
QgsAccessControl()
Constructor.
QgsAccessControl(const QgsAccessControl &copy)
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).
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Definition qgsfeature.h:58
Base class for all map layer types.
Definition qgsmaplayer.h:76
Represents a vector layer which manages a vector based data sets.
