Class: QgsAbstractProviderConnection¶

The QgsAbstractProviderConnection provides an interface for data provider connections.

Connections objects can be constructed loading them from the connections stored in the settings by passing the connection name. A new connection object can also be created by passing a data source URI in the constructor.

Provider metadata keep a cache of the existing connections, to manage stored connections it is recommendend to call metadata methods instead of loading and storing the connections directly.

Concrete classes must implement methods to retrieve, save and remove connections from the settings.

Added in version 3.10.
