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 calling QgsProcessingAlgorithm.parameterAsConnectionName().

New in version 3.14.

QgsProcessingParameterProviderConnection(name: str, description: str, provider: str, defaultValue: Any = None, optional: bool = False) Constructor for QgsProcessingParameterProviderConnection, for the specified provider 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.
