GeometryOperationResult
Success or failure of a geometry operation.
Definition: qgis.h:624
Abstract base class for all geometries.
Abstract base class for curved geometry type.
Definition: qgscurve.h:36
Convenience functions for geometry editing.
static Qgis::GeometryOperationResult addRing(QgsAbstractGeometry *geometry, std::unique_ptr< QgsCurve > ring)
Add an interior ring to a geometry.

Alters a geometry so that it avoids intersections with features from all open vector layers.
static bool deletePart(QgsAbstractGeometry *geom, int partNum)
Deletes a part from a geometry.
static bool deleteRing(QgsAbstractGeometry *geom, int ringNum, int partNum=0)
Deletes a ring from a geometry.
static Qgis::GeometryOperationResult addPart(QgsAbstractGeometry *geometry, std::unique_ptr< QgsAbstractGeometry > part)
Add a part to multi type geometry.
A geometry engine is a low-level representation of a QgsAbstractGeometry object, optimised for use wi...
Represents a vector layer which manages a vector based data sets.
