      • nextDesktopId

        public java.lang.String nextDesktopId​(Desktop desktop)
        Description copied from interface: IdGenerator
        Returns the next desktop ID for the specified desktop, or null to generate the default ID.

        Default (if null is returned): ID is generated randomly. In other words, the desktop's ID, by default, is not deterministic. To have a deterministic value, you have to implement this method.

        Notice that UUID cannot be empty and can only have alphanumeric characters or underscore (i.e., a-z, A-Z, 0-9, and _).

        Also notice that we can retrieve the execution by use of Desktop.getExecution(), or Executions.getCurrent().

        Specified by:
        nextDesktopId in interface IdGenerator
        Returns:
        the next desktop ID, or null to generate the default ID.
