@ Polygon
Polygons.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition qgsfeedback.h:45
Base configuration for geometry checks.
This represents an error reported by a geometry check.
QgsFeatureId featureId() const
The id of the feature on which this error has been detected.
const QgsGeometryCheck * check() const
The geometry check that created this error.
const QString & layerId() const
The id of the layer on which this error has been detected.
This class implements a geometry check.
CheckType
The type of a check.
A layer feature combination to uniquely identify and access a feature in a set of layers.
A duplicate geometry check error.
bool isEqual(QgsGeometryCheckError *other) const override
Returns if the other error is equivalent.
QMap< QString, QList< QgsFeatureId > > duplicates() const
Returns the duplicates.
QgsGeometryDuplicateCheckError(const QgsGeometryCheck *check, const QgsGeometryCheckerUtils::LayerFeature &layerFeature, const QgsPointXY &errorLocation, const QMap< QString, QgsFeaturePool * > &featurePools, const QMap< QString, QList< QgsFeatureId > > &duplicates)
Constructor.
A duplicate geometry check.
static bool factoryIsCompatible(QgsVectorLayer *layer)
static QList< Qgis::GeometryType > factoryCompatibleGeometryTypes()
QList< Qgis::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.
QString description() const override
Returns a human readable description for this check.
QgsGeometryDuplicateCheck(QgsGeometryCheckContext *context, const QVariantMap &configuration)
A class to represent a 2D point.
Definition qgspointxy.h:59
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.
Definition qgsvertexid.h:31
