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.
A geometry type check error.
QgsGeometryTypeCheckError(const QgsSingleGeometryCheck *check, const QgsGeometry &geometry, const QgsGeometry &errorLocation, QgsWkbTypes::Type flatType)
A geometry type check.
static QList< QgsWkbTypes::GeometryType > factoryCompatibleGeometryTypes()
QList< QgsWkbTypes::GeometryType > compatibleGeometryTypes() const override
A list of geometry types for which this check can be performed.
QgsGeometryTypeCheck(QgsGeometryCheckContext *context, const QVariantMap &configuration, int allowedTypes)
static bool factoryIsCompatible(QgsVectorLayer *layer)
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 QString description() const
A human readable description of this error.
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.
Type
The WKB type describes the number of dimensions a geometry has.
