java.util.EventObject

com.vaadin.flow.server.communication.UIResynchronizationEvent

All Implemented Interfaces:

Serializable

public class UIResynchronizationEvent
extends EventObject

Event fired through the service event bus when the client asks the server to resynchronize a UI, on the request thread while the session is locked and before the UI is resynchronized.

The client asks for a resynchronization when it detects that it missed a message from the server, typically because of a bad network connection or a push connection that was closed by a proxy. The server then sends the full state of the UI to the client.

Since:

25.4
