QgsGeometrySelfIntersectionCheck(const QgsGeometryCheckContext *context, const QVariantMap &configuration=QVariantMap())
QList< QgsWkbTypes::GeometryType > compatibleGeometryTypes() const override
A list of geometry types for which this check can be performed.
virtual bool isEqual(const QgsSingleGeometryCheckError *other) const
Check if this error is equal to other.
CheckType
The type of a check.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:111
QgsGeometrySelfIntersectionCheckError(const QgsSingleGeometryCheck *check, const QgsGeometry &geometry, const QgsGeometry &errorLocation, QgsVertexId vertexId, const QgsGeometryUtils::SelfIntersection &intersection)
Base class for geometry checks for a single geometry without any context of the layer or other layers...
QString description() const override
Returns a human readable description for this check.
virtual bool handleChanges(const QList< QgsGeometryCheck::Change > &changes)
Apply a list of changes.
Base configuration for geometry checks.
QgsGeometryCheck::Flags flags() const override
Flags for this geometry check.
Utility class for identifying a unique vertex within a geometry.
#define SIP_SKIP
Definition: qgis_sip.h:119
An error from a QgsSingleGeometryCheck.
QMap< QString, QMap< QgsFeatureId, QList< QgsGeometryCheck::Change > > > Changes
A collection of changes.
QString id() const override
Returns an id for this check.
virtual void fixError(const QMap< QString, QgsFeaturePool *> &featurePools, QgsGeometryCheckError *error, int method, const QMap< QString, int > &mergeAttributeIndices, Changes &changes) const
Fix the error error with the specified method.
virtual QList< QgsSingleGeometryCheckError * > processGeometry(const QgsGeometry &geometry) const =0
Check the geometry for errors.
QgsGeometryCheck::CheckType checkType() const override
Returns the check type.
virtual QStringList resolutionMethods() const =0
Returns a list of descriptions for available resolutions for errors.
This represents an error reported by a geometry check.
Represents a vector layer which manages a vector based data sets.
virtual void update(const QgsSingleGeometryCheckError *other)
Update this error with the information from other.
