Class: QgsGeometryCheckError¶

This represents an error reported by a geometry check.

Note

This class is a technology preview and unstable API.

Added in version 3.4.

Class Hierarchy¶

Subclasses¶

QgsGeometryCheckErrorSingle

Wraps a QgsSingleGeometryError into a standard QgsGeometryCheckError. The single error can be obtained via singleError.

Methods

`check`	The geometry check that created this error.
`featureId`	The id of the feature on which this error has been detected.
`geometry`	The geometry of the error in map units.
`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.
`value`	An additional value for the error.
`valueType`	The type of the value.
`vidx`	The id of the affected vertex.

Virtual Methods

In PyQGIS, only methods marked as virtual can be safely overridden in a Python subclass of QgsGeometryCheckError. See the FAQ for more details.

`affectedAreaBBox`	The bounding box of the affected area of the error.
`closeMatch`	Check if this error is almost equal to other.
`contextBoundingBox`	The context of the error.
`description`	The error description.
`icon`	Returns an icon that should be shown for this kind of error.
`isEqual`	Check if this error is equal to other.
`update`	Update this error with the information from other.

class qgis.analysis.QgsGeometryCheckError[source]¶

Bases: object

__init__(check: QgsGeometryCheck | None, 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.

Parameters:

check (Optional[QgsGeometryCheck])
layerFeature (QgsGeometryCheckerUtils.LayerFeature)
errorLocation (QgsPointXY)
vidx (QgsVertexId = QgsVertexId())
value (Any = None)
valueType (QgsGeometryCheckError.ValueType = QgsGeometryCheckError.ValueOther)

__init__(check: QgsGeometryCheck | None, layerId: str | None, 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.

Parameters:

check (Optional[QgsGeometryCheck])
layerId (Optional[str])
featureId (int)
geometry (QgsGeometry)
errorLocation (QgsPointXY)
vidx (QgsVertexId = QgsVertexId())
value (Any = None)
valueType (QgsGeometryCheckError.ValueType = QgsGeometryCheckError.ValueOther)

__init__(a0: QgsGeometryCheckError)

Parameters:: a0 (QgsGeometryCheckError)

class ValueType¶: Bases: int

virtual affectedAreaBBox(self) → QgsRectangle[source]¶

The bounding box of the affected area of the error.

Return type:: QgsRectangle

check(self) → QgsGeometryCheck | None[source]¶

The geometry check that created this error.

Return type:: Optional[QgsGeometryCheck]

virtual closeMatch(self, a0: QgsGeometryCheckError | None) → bool[source]¶

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

Parameters:: a0 (Optional[QgsGeometryCheckError])
Return type:: bool

virtual contextBoundingBox(self) → QgsRectangle[source]¶

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.

Added in version 3.10.

Return type:: QgsRectangle

virtual description(self) → str[source]¶

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

Return type:: str

featureId(self) → int[source]¶

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

Return type:: int

geometry(self) → QgsGeometry[source]¶

The geometry of the error in map units.

Return type:: QgsGeometry

virtual icon(self) → QIcon[source]¶

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

Added in version 3.8.

Return type:: QIcon

virtual isEqual(self, other: QgsGeometryCheckError | None) → bool[source]¶

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 (Optional[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[source]¶

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

Return type:: str

setFixFailed(self, reason: str | None)[source]¶

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

Parameters:: reason (Optional[str])

setFixed(self, method: int)[source]¶

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

Parameters:: method (int)

setObsolete(self)[source]¶: Set the error status to obsolete.

status(self) → QgsGeometryCheckError.Status[source]¶

The status of the error.

Return type:: QgsGeometryCheckError.Status

virtual update(self, other: QgsGeometryCheckError | None)[source]¶

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

Parameters:: other (Optional[QgsGeometryCheckError])

value(self) → Any[source]¶

An additional value for the error. Lengths and areas are provided in map units.
