NAME

       Path - record of connectors visited during dataflow

SYNOPSIS

       #include <Unidraw/path.h>

DESCRIPTION

       A  Path  object  stores  a  record  of  connectors that have been visited during dataflow.
       Transfer functions,  state  variables,  connectors,  and  other  components  can  use  the
       information  in  the path to determine whether data should be transmitted, for example, to
       avoid circular flow.

PUBLIC OPERATIONS

       Path(Path* = nil)
              Instantiate a new path, optionally with a duplicate of the information contained in
              the given path.

       virtual void Visit(Connector*)
              Register a connector as having been visited.

       virtual boolean Visited(Connector*)
              Return whether or not a connector has been registered previously with the path.
