Description

The type of the TMQTTClient.Subscriptions property. Maintains a list of TMQTTClientSubscription components that have been instantiated and are assigned to this TMQTTClient object. This list is maintained automatically.

When a session is established and it is a clean session or the server indicates it did not find an existing connection in its datastores, then the Client.InitSession method is called. This method uses the Subscriptions property to automatically subscribe to various topic filters.

Use this list to inspect or find TMQTTClientSubscription components for an MQTT client connection. TMQTTClientSubscription objects are added/removed from this list by setting their Client property or by calling their destructors.
