PreferencesChangeType

class negmas.common.PreferencesChangeType(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)[source]

Bases: Enum

The type of change in preferences.

Remarks:

Returned from changes property of Preferences to help the owner of the preferences in deciding what to do with the change.

Received by the on_preferences_changed method of Rational entities to inform them about a change in preferences.

Note that the Rational entity needs to call changes explicitly and call its own on_preferences_changed to handle changes that happen without assignment to preferences of the Rational entity.

If the preferences of the Rational agent are changed through assignment, its on_preferences_changed will be called with the appropriate PreferencesChange list.
