Class: QgsSingleGeometryCheck

class qgis.analysis.QgsSingleGeometryCheck(context: QgsGeometryCheckContext, configuration: Dict[str, Any])

Bases: qgis._analysis.QgsGeometryCheck

Creates a new single geometry check.

QgsSingleGeometryCheck(QgsSingleGeometryCheck)

Base class for geometry checks for a single geometry without any context of the layer or other layers in the project. Classic examples are validity checks like self-intersection.

Subclasses need to implement the processGeometry method.

New in version 3.4: Enums

collectErrors(self, featurePools: object, errors: Iterable[QgsGeometryCheckError], messages: Iterable[str], feedback: QgsFeedback = None, ids: QgsGeometryCheck.LayerFeatureIds = QgsGeometryCheck.LayerFeatureIds())
processGeometry(self, geometry: QgsGeometry) → object

Check the geometry for errors. It may make use of configuration options.

Returns a list of QgsSingleGeometryCheckErrors, ownership is transferred to the caller. An empty list is returned for geometries without errors.
