QString id() const override
Returns an id for this check.
QgsGeometryDuplicateNodesCheck(QgsGeometryCheckContext *context, const QVariantMap &configuration)
QgsGeometryCheck::CheckType checkType() const override
Returns the check type.
Base configuration for geometry checks.
CheckType
The type of a check.
Base class for feedback objects to be used for cancellation of something running in a worker thread...
Definition: qgsfeedback.h:44
#define SIP_SKIP
Definition: qgis_sip.h:126
This class implements a geometry check.
A list of layers and feature ids for each of these layers.
QMap< QString, QMap< QgsFeatureId, QList< QgsGeometryCheck::Change > > > Changes
A collection of changes.
static QList< QgsWkbTypes::GeometryType > factoryCompatibleGeometryTypes()
virtual void fixError(const QMap< QString, QgsFeaturePool *> &featurePools, QgsGeometryCheckError *error, int method, const QMap< QString, int > &mergeAttributeIndices, Changes &changes) const
Fixes the error error with the specified method.
virtual QStringList resolutionMethods() const =0
Returns a list of descriptions for available resolutions for errors.
QList< QgsWkbTypes::GeometryType > compatibleGeometryTypes() const override
A list of geometry types for which this check can be performed.
This represents an error reported by a geometry check.
virtual void collectErrors(const QMap< QString, QgsFeaturePool *> &featurePools, QList< QgsGeometryCheckError *> &errors, QStringList &messages, QgsFeedback *feedback, const LayerFeatureIds &ids=QgsGeometryCheck::LayerFeatureIds()) const =0
The main worker method.
QString description() const override
Returns a human readable description for this check.
Represents a vector layer which manages a vector based data sets.
