A message contains the actual data object which is sent by the publisher and delivered to the interested subscribers for the topic. NCache provides the Message class which implements the IMessage interface to create a message.

The ITopic interface facilitates creating subscription and publishing of messages against the topic. This also provides event registrations for message delivery failure, receiving messages and deleting topics.

NCache provides ITopicSubscription interface which is returned against the desired topic, containing information for topic subscriptions.

Represents client connectivity status.

NCache provides a DeliveryOption enum which specifies how the message should be delivered to any registered subscribers. The delivery option is specified during message publishing phase. It contains the following options:

The type of expiration to be used while expiring items in cache. The value of this type varies from item to item in cache.

The reason for failed message delivery.

Enumeration that defines the read mode if item is not found in cache.

Enumeration that defines the staus of write behind operation.

Enumeration that defines the update operation on cache can update data source.

Delivery failure notification is raised to any publisher which has registered message failure event on that topic.
