Abstract base class for all geometries.
static int addPart(QgsAbstractGeometryV2 *geom, QgsAbstractGeometryV2 *part)
Adds part to multi type geometry (taking ownership)
static bool deletePart(QgsAbstractGeometryV2 *geom, int partNum)
Deletes a part from a geometry.
static bool deleteRing(QgsAbstractGeometryV2 *geom, int ringNum, int partNum=0)
Deletes a ring from a geometry.
static QgsAbstractGeometryV2 * avoidIntersections(const QgsAbstractGeometryV2 &geom, QMap< QgsVectorLayer *, QSet< QgsFeatureId > > ignoreFeatures=(QMap< QgsVectorLayer *, QSet< QgsFeatureId > >()))
Alters a geometry so that it avoids intersections with features from all open vector layers...
static int addRing(QgsAbstractGeometryV2 *geom, QgsCurveV2 *ring)
Adds interior ring (taking ownership).
Contains geometry relation and modification algorithms.
Abstract base class for curved geometry type.
Definition: qgscurvev2.h:32
Represents a vector layer which manages a vector based data sets.
Convenience functions for geometry editing.
