Module: Audiences::Notifications

Defined in:
lib/audiences/notifications.rb

Overview

Handles notification of audience context changes. The notifications handled by this module are related to the membership composition of a context.

For instance, when a user leaves a group, the app will be notified of changes to the members of that context so it can react to that. When the audience configuration of a context changes, a notification will also be published through ‘Audiences::Notifications`.
