Attributes

asScriptCode(self) → str
checkValueIsAcceptable(self, input: Any, context: QgsProcessingContext = None) → bool
clone(self) → QgsProcessingParameterDefinition
dataType(self) → QgsProcessing.SourceType

Returns the layer type for sinks associated with the parameter.

setDataType()

defaultFileExtension(self) → str
fromScriptCode(name: str, description: str, isOptional: bool, definition: str) → QgsProcessingParameterFeatureSink

Creates a new parameter using the definition from a script code.

fromVariantMap(self, map: Dict[str, Any]) → bool
generateTemporaryDestination(self) → str
hasGeometry(self) → bool

Returns true if sink is likely to include geometries. In cases were presence of geometry cannot be reliably determined in advance, this method will default to returning true.

setDataType(self, type: QgsProcessing.SourceType)

Sets the layer type for the sinks associated with the parameter.
