        Specified by:
        changeVariables in interface VariableOwner

      • isEnabled

        public boolean isEnabled()
        Deprecated.

        Tests if the variable owner is enabled or not. The terminal should not send any variable changes to disabled variable owners.

        Implementation detail: this method is originally from the VariableOwner class, which has been removed in Vaadin 8.
        Specified by:
        isEnabled in interface VariableOwner
        Returns:
        true if the variable owner is enabled, false if not

        Checks if the communicator is enabled. An enabled communicator is allowed to receive messages from its counter-part.
        Specified by:
        isConnectorEnabled in interface ClientConnector
        Returns:
        true if the connector can receive messages, false otherwise

      • markAsDirtyRecursive

        public void markAsDirtyRecursive()
        Deprecated.
        Description copied from interface: ClientConnector
        Causes this connector and all connectors below it to be marked as dirty.

        This should only be used in special cases, e.g when the state of a descendant depends on the state of an ancestor.

        Specified by:
        markAsDirtyRecursive in interface ClientConnector
        See Also:
        ClientConnector.markAsDirty()

      • attach

        public void attach()
        Deprecated.
        Description copied from interface: ClientConnector
        Notifies the connector that it is connected to a VaadinSession (and therefore also to a UI).

        The caller of this method is Component.setParent(HasComponents) if the parent is itself already attached to the session. If not, the parent will call the ClientConnector.attach() for all its children when it is attached to the session. This method is always called before the connector's data is sent to the client-side for the first time.

        The attachment logic is implemented in AbstractClientConnector.

        Specified by:
        attach in interface ClientConnector

      • removeExtension

        public void removeExtension​(Extension extension)
        Deprecated.
        Description copied from interface: ClientConnector
        Remove an extension from this connector.
        Specified by:
        removeExtension in interface ClientConnector
        Parameters:
        extension - the extension to remove.

      • getUI

        public UI getUI()
        Deprecated.
        Description copied from interface: ClientConnector
        Returns the UI this connector is attached to.
        Specified by:
        getUI in interface ClientConnector
        Returns:
        The UI this connector is attached to or null if it is not attached to any UI

      • beforeClientResponse

        public void beforeClientResponse​(boolean initial)
        Deprecated.
        Description copied from interface: ClientConnector
        Called before the shared state and RPC invocations are sent to the client. Gives the connector an opportunity to set computed/dynamic state values or to invoke last minute RPC methods depending on other component features.
        Specified by:
        beforeClientResponse in interface ClientConnector
        Parameters:
        initial - true if the client-side connector will be created and initialized after this method has been invoked. false if there is already an initialized client-side connector.

      • handleConnectorRequest

        public boolean handleConnectorRequest​(VaadinRequest request,
                                      VaadinResponse response,
                                      String path)
                               throws IOException
        Deprecated.
        Description copied from interface: ClientConnector
        Handle a request directed to this connector. This can be used by connectors to dynamically generate a response and it is also used internally when serving ConnectorResources.

        Requests to /APP/connector/[ui id]/[connector id]/ are routed to this method with the remaining part of the requested path available in the path parameter.

        NOTE that the session is not locked when this method is called. It is the responsibility of the connector to ensure that the session is locked while handling state or other session related data. For best performance the session should be unlocked before writing a large response to the client.

        Specified by:
        handleConnectorRequest in interface ClientConnector
        Parameters:
        request - the request that should be handled
        response - the response object to which the response should be written
        path - the requested relative path
        Returns:
        true if the request has been handled, false if no response has been written.
        Throws:
        IOException - if there is a problem generating a response.
