Interface MigratoryDataInteractiveListener

All Superinterfaces:

MigratoryDataListener

public interface MigratoryDataInteractiveListener
extends MigratoryDataListener

Implementations of this interface handle data messages and status notifications, like implementations of MigratoryDataListener do, and furthermore handle subscription events for the advertised interactive subjects.

Use the API method MigratoryDataClient.setListener(MigratoryDataListener) to register your interactive listener implementation.

Note: The subscription events — consisting of the first subscribe and last unsubscribe events — applies only for the subjects which match one of the wildcard subjects advertised with the API method MigratoryDataClient.advertiseInteractiveSubjects(List), and provided that the Interactive Publishing extension is enabled in the MigratoryData server, i.e. the parameter Extension.InteractivePublishing of the MigratoryData server is set on true.
