settings

Generic strategy for adding configurations to the session.

NoneType = type(None) module-attribute

SettingsConfig

Bases: AttrDict

Configuration for a generic "settings" filter.

This strategy stores settings in the session such that they are available for other strategies. For this to work, this strategy should be added to the end of the pipeline (since it uses the initiate() method).

The settings are stored as a JSON string which can be accessed by its label.
