Base configuration for geometry checks.
This represents an error reported by a geometry check.
This class implements a geometry check.
CheckType
The type of a check.

QgsGeometrySelfIntersectionCheckError(const QgsSingleGeometryCheck *check, const QgsGeometry &geometry, const QgsGeometry &errorLocation, QgsVertexId vertexId, const QgsGeometryUtils::SelfIntersection &intersection)
QgsGeometryCheck::Flags flags() const override
Flags for this geometry check.
QString description() const override
Returns a human readable description for this check.
QList< QgsWkbTypes::GeometryType > compatibleGeometryTypes() const override
A list of geometry types for which this check can be performed.
QgsGeometryCheck::CheckType checkType() const override
Returns the check type.
QString id() const override
Returns an id for this check.
QgsGeometrySelfIntersectionCheck(const QgsGeometryCheckContext *context, const QVariantMap &configuration=QVariantMap())
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:125
An error from a QgsSingleGeometryCheck.
virtual bool isEqual(const QgsSingleGeometryCheckError *other) const
Check if this error is equal to other.
virtual bool handleChanges(const QList< QgsGeometryCheck::Change > &changes)
Apply a list of changes.
virtual void update(const QgsSingleGeometryCheckError *other)
Update this error with the information from other.
Base class for geometry checks for a single geometry without any context of the layer or other layers...
Represents a vector layer which manages a vector based data sets.
#define SIP_SKIP
Definition: qgis_sip.h:126
Utility class for identifying a unique vertex within a geometry.
