Class: QgsGeometryCheckerUtils

Contains utilities required for geometry checks.

Note

This class is a technology preview and unstable API.

Added in version 3.4.

class qgis.analysis.QgsGeometryCheckerUtils

Bases: object

class LayerFeature

Bases: object

A layer feature combination to uniquely identify and access a feature in a set of layers.

Added in version 3.4.

QgsGeometryCheckerUtils.LayerFeature(pool: Optional[QgsFeaturePool], feature: QgsFeature, context: Optional[QgsGeometryCheckContext], useMapCrs: bool) Create a new layer/feature combination. The layer is defined by pool, feature needs to be from this layer. If useMapCrs is True, geometries will be reprojected to the mapCrs defined in context.

QgsGeometryCheckerUtils.LayerFeature(a0: QgsGeometryCheckerUtils.LayerFeature)

feature(self) → QgsFeature

Returns the feature. The geometry will not be reprojected regardless of useMapCrs.

Return type:

QgsFeature

geometry(self) → QgsGeometry

Returns the geometry of this feature. If useMapCrs was specified, it will already be reprojected into the CRS specified in the context specified in the constructor.

Return type:

QgsGeometry

id(self) → str

Returns a combination of the layerId and the feature id.

Return type:

str

layerId(self) → str

The layer id.

Return type:

str

useMapCrs(self) → bool

Returns if the geometry is reprojected to the map CRS or not.

Return type:

bool

class LayerFeatures

Bases: object

Contains a set of layers and feature ids in those layers to pass to a geometry check.
