Class: QgsGeometryCheckError

class qgis.analysis.QgsGeometryCheckError

Bases: sip.wrapper

This represents an error reported by a geometry check.

Note

This class is a technology preview and unstable API.

New in version 3.4.

QgsGeometryCheckError(check: QgsGeometryCheck, layerFeature: QgsGeometryCheckerUtils.LayerFeature, errorLocation: QgsPointXY, vidx: QgsVertexId = QgsVertexId(), value: Any = None, valueType: QgsGeometryCheckError.ValueType = QgsGeometryCheckError.ValueOther) Create a new geometry check error with the parent check and for the layerFeature pair at the errorLocation. Optionally the vertex can be specified via vixd and a value with its value Type for additional information.

QgsGeometryCheckError(check: QgsGeometryCheck, layerId: str, featureId: int, geometry: QgsGeometry, errorLocation: QgsPointXY, vidx: QgsVertexId = QgsVertexId(), value: Any = None, valueType: QgsGeometryCheckError.ValueType = QgsGeometryCheckError.ValueOther) Create a new geometry check error with the parent check and for the layer with layerId and featureId. The geometry of the error and the errorLocation need to be specified in map coordinates. Optionally the vertex can be specified via vixd and a value with its value Type for additional information.

QgsGeometryCheckError(QgsGeometryCheckError)

Methods

affectedAreaBBox

The bounding box of the affected area of the error.

check

The geometry check that created this error.

closeMatch

Check if this error is almost equal to other.

contextBoundingBox

The context of the error.

description

The error description.

featureId

The id of the feature on which this error has been detected.

geometry

The geometry of the error in map units.

icon

Returns an icon that should be shown for this kind of error.

isEqual

Check if this error is equal to other.

layerId

The id of the layer on which this error has been detected.

location

The location of the error in map units.

resolutionMessage

A message with details, how the error has been resolved.

setFixFailed

Set the error status to failed and specify the reason for failure.

setFixed

Set the status to fixed and specify the method that has been used to fix the error.

setObsolete

Set the error status to obsolete.

status

The status of the error.

update

class ValueType

Bases: int

affectedAreaBBox(self) QgsRectangle

The bounding box of the affected area of the error.

Return type:

QgsRectangle

check(self) QgsGeometryCheck

The geometry check that created this error.

Return type:

QgsGeometryCheck

closeMatch(self, QgsGeometryCheckError) bool

Check if this error is almost equal to other. If this returns True, it can be used to update existing errors after re-checking.

Return type:

bool

contextBoundingBox(self) QgsRectangle

The context of the error. For topology checks like gap checks this returns the context of an error and the involved features. May be a NULL rectangle.

New in version 3.10.

Return type:

QgsRectangle

description(self) str

The error description. By default the description of the parent check will be returned.

Return type:

str

featureId(self) int

The id of the feature on which this error has been detected.

Return type:

int

geometry(self) QgsGeometry

The geometry of the error in map units.

Return type:

QgsGeometry

icon(self) QIcon

Returns an icon that should be shown for this kind of error.

New in version 3.8.

Return type:

QIcon

isEqual(self, other: QgsGeometryCheckError) bool

Check if this error is equal to other. Is reimplemented by subclasses with additional information, comparison of base information is done in parent class.

Parameters:

other (QgsGeometryCheckError) –

Return type:

bool

layerId(self) str

The id of the layer on which this error has been detected.

Return type:

str

location(self) QgsPointXY

The location of the error in map units.

Return type:

QgsPointXY

resolutionMessage(self) str

A message with details, how the error has been resolved.

Return type:

str

setFixFailed(self, reason: str)

Set the error status to failed and specify the reason for failure.

Parameters:

reason (str) –

setFixed(self, method: int)

Set the status to fixed and specify the method that has been used to fix the error.

Parameters:

method (int) –

setObsolete(self)

Set the error status to obsolete.

status(self) QgsGeometryCheckError.Status

The status of the error.

Return type:

QgsGeometryCheckError.Status

update(self, other: QgsGeometryCheckError)

Update this error with the information from other. Will be used to update existing errors whenever they are re-checked.
