        public void setFlow​(java.util.Vector v)
             throws java.lang.Exception
        Set the flow for the KnowledgeFlow to edit. Assumes that client has loaded a Vector of beans and a Vector of connections. the supplied beans and connections are deep-copied via serialization before being set in the layout.
        Parameters:
        v - a Vector containing a Vector of beans and a Vector of connections
