Method Detail

setRequestContext

public void setRequestContext(RequestContext request)

subscribe

public HandlerRegistration subscribe()

Description copied from interface: EditorDelegate

Register for notifications if object being edited is updated. Not all backends support subscriptions and will return null.

The notification will occur via ValueAwareEditor.onPropertyChange(java.lang.String...) if the backend supports in-place property updates, otherwise updates will be passed via ValueAwareEditor.setValue(T).

Specified by:

subscribe in interface EditorDelegate<P>

Specified by:

subscribe in class AbstractEditorDelegate<P,E extends Editor<P>>

Returns:

a HandlerRegistration to unsubscribe from the notifications or null if the delegate does not support subscription
