transformContext (QgsCoordinateTransformContext = QgsCoordinateTransformContext()) –

loadDefaultStyle
skipCrsValidation

attributes(self) → QgsPointCloudAttributeCollection

Returns the attributes available from the layer.

Return type

QgsPointCloudAttributeCollection

childEvent(self, QChildEvent)
clone(self) → QgsPointCloudLayer
Return type

QgsPointCloudLayer

connectNotify(self, QMetaMethod)
createMapRenderer(self, rendererContext: QgsRenderContext) → QgsMapLayerRenderer
Parameters

rendererContext (QgsRenderContext) –

Return type

QgsMapLayerRenderer

customEvent(self, QEvent)
dataProvider(self) → QgsPointCloudDataProvider
Return type

QgsPointCloudDataProvider

decodedSource(self, source: str, dataProvider: str, context: QgsReadWriteContext) → str

Called by readLayerXML(), used by derived classes to decode provider’s specific data source from project files. Typically resolving absolute or relative paths, usernames and passwords or drivers prefixes (“HDF5:”)

Parameters

  • source – data source to decode, typically read from layer’s DOM element “datasource”

  • dataProvider – string identification of data provider (e.g. “ogr”), typically read from layer’s DOM element

  • context – reading context (e.g. for conversion between relative and absolute paths)

Returns

decoded source, typically to be used as the layer’s datasource

New in version 3.2.

disconnectNotify(self, QMetaMethod)
elevationProperties(self) → QgsMapLayerElevationProperties
Return type

QgsMapLayerElevationProperties

encodedSource(self, source: str, context: QgsReadWriteContext) → str

Called by writeLayerXML(), used by derived classes to encode provider’s specific data source to project files. Typically resolving absolute or relative paths, usernames and passwords or drivers prefixes (“HDF5:”)

Parameters

  • source – data source to encode, typically QgsMapLayer.source()

  • context – writing context (e.g. for conversion between relative and absolute paths)

Returns

encoded source, typically to be written in the DOM element “datasource”

New in version 3.2.

extent(self) → QgsRectangle
Return type

QgsRectangle

hasDependencyCycle(self, Iterable[QgsMapLayerDependency]) → bool

Checks whether a new set of dependencies will introduce a cycle this method is now deprecated and always return False, because circular dependencies are now correctly managed.

Deprecated since version QGIS: 3.10

Return type

str

New in version 3.0.

readCustomProperties(self, layerNode: QDomNode, keyStartsWith: str = '')

Read custom properties from project file.

Parameters

  • layerNode – note to read from

  • keyStartsWith – reads only properties starting with the specified string (or all if the string is empty)
