GeometryType
The geometry types are used to group Qgis::WkbType in a coarse way.
virtual QgsPoint centroid() const
Returns the centroid of the geometry.
A feature pool is based on a vector layer and caches features.
virtual void deleteFeature(QgsFeatureId fid)=0
Removes a feature from this pool.
bool getFeature(QgsFeatureId id, QgsFeature &feature)
Retrieves the feature with the specified id into feature.
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Base class for feedback objects to be used for cancellation of something running in a worker thread.
const double tolerance
The tolerance to allow for in 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.
void setFixed(int method)
Set the status to fixed and specify the method that has been used to fix the error.
void setFixFailed(const QString &reason)
Set the error status to failed and specify the reason for failure.
QVariant value() const
An additional value for the error.
void setObsolete()
Set the error status to obsolete.
const QString & layerId() const
The id of the layer on which this error has been detected.
QMap< QString, QMap< QgsFeatureId, QList< QgsGeometryCheck::Change > > > Changes
A collection of changes.
const QgsGeometryCheckContext * mContext
@ ChangeFeature
This change happens on feature level.
CheckType
The type of a check.
@ FeatureCheck
The check controls geometries as a whole.
QMap< QString, QgsFeatureIds > allLayerFeatureIds(const QMap< QString, QgsFeaturePool * > &featurePools) const
Returns all layers and feature ids.
@ ChangeRemoved
Something has been removed.
A layer feature combination to uniquely identify and access a feature in a set of layers.
QgsGeometry geometry() const
Returns the geometry of this feature.
Contains a set of layers and feature ids in those layers to pass to a geometry check.
static std::unique_ptr< QgsGeometryEngine > createGeomEngine(const QgsAbstractGeometry *geometry, double tolerance)
A duplicate geometry check error.
QMap< QString, QList< QgsFeatureId > > duplicates() const
Returns the duplicates.
static QgsGeometryCheck::CheckType factoryCheckType()
static QString factoryId()
QList< Qgis::GeometryType > compatibleGeometryTypes() const override

Q_DECL_DEPRECATED QStringList resolutionMethods() const override
Returns a list of descriptions for available resolutions for errors.
void fixError(const QMap< QString, QgsFeaturePool * > &featurePools, QgsGeometryCheckError *error, int method, const QMap< QString, int > &mergeAttributeIndices, Changes &changes) const override
Fixes the error error with the specified method.
void collectErrors(const QMap< QString, QgsFeaturePool * > &featurePools, QList< QgsGeometryCheckError * > &errors, QStringList &messages, QgsFeedback *feedback, const LayerFeatureIds &ids=LayerFeatureIds()) const override
The main worker method.
A geometry is the spatial representation of a feature.
const QgsAbstractGeometry * constGet() const
Returns a non-modifiable (const) reference to the underlying abstract geometry primitive.
QgsRectangle boundingBox() const
Returns the bounding box of the geometry.
A rectangle specified with double values.
qint64 QgsFeatureId
64 bit feature ids negative numbers are used for uncommitted/newly added features
Descripts a change to fix a geometry.
A list of layers and feature ids for each of these layers.
