Class: QgsProcessingParameterProviderConnection¶
- class qgis.core.QgsProcessingParameterProviderConnection¶
Bases:
QgsProcessingParameterDefinition
A data provider connection parameter for processing algorithms, allowing users to select from available registered connections for a particular data provider.
QgsProcessingParameterProviderConnection
should be evaluated by callingQgsProcessingAlgorithm.parameterAsConnectionName()
.New in version 3.14.
QgsProcessingParameterProviderConnection(name: str, description: str, provider: str, defaultValue: Any = None, optional: bool = False) Constructor for
QgsProcessingParameterProviderConnection
, for the specifiedprovider
type.Warning
The provider must support the connection API methods in its
QgsProviderMetadata
implementation in order for the model to work correctly. This is only implemented for a subset of current data providers.QgsProcessingParameterProviderConnection(
