QgsGeometryIsValidCheck class

Checks if geometries are valid using the backend configured in the QGIS settings.

This does not offer any fixes but makes sure that all geometries are valid.

Base classes

class QgsSingleGeometryCheck: Base class for geometry checks for a single geometry without any context of the layer or other layers in the project.

QgsGeometryIsValidCheck(const QgsGeometryCheckContext* context, const QVariantMap& configuration) explicit: Creates a new is valid check with the provided context.

auto checkType() const -> QgsGeometryCheck::CheckType override: Returns the check type.
auto compatibleGeometryTypes() const -> QList<QgsWkbTypes::GeometryType> override: A list of geometry types for which this check can be performed.
auto description() const -> QString override: Returns a human readable description for this check.
auto id() const -> QString override: Returns an id for this check.
auto processGeometry(const QgsGeometry& geometry) const -> QList<QgsSingleGeometryCheckError*> override: Check the geometry for errors.
auto resolutionMethods() const -> QStringList override: Returns a list of descriptions for available resolutions for errors.

Creates a new is valid check with the provided context.

No options are supported in configuration.

Returns the check type.

A list of geometry types for which this check can be performed.

Returns a human readable description for this check.

Returns an id for this check.

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.

Returns a list of descriptions for available resolutions for errors.
