taipy.core.notification

Package for notifications about changes on Core service entities.

The Core service generates Event objects to track changes on entities. These events are then relayed to a Notifier, which handles the dispatch to consumers interested in specific event topics.

To subscribe, a consumer needs to invoke the Notifier.register() method. This call will yield a RegistrationId and a dedicated event queue for receiving notifications.

To handle notifications, an event consumer (e.g., the CoreEventConsumerBase object) must be instantiated with an associated event queue.

Types

• RegistrationId: Registration identifier. It can be used to instantiate a CoreEventConsumerBase.

Classes

• CoreEventConsumerBase: Abstract base class for implementing a Core event consumer.
• Event: Event object used to notify any change in the Core service.
• EventEntityType: Enum representing an entity type.
• EventOperation: Enum representing a type of operation performed on a Core entity.
• Notifier: A class for managing event registrations and publishing Core service events.
