 Dataflow link
 ++++++++++++++++++++++++++++
-The first step in defining a dataflow link is to obtain port objects using one of the methods described above.  
-The edAddDFLink method for the context node is then used, transferring the two ports to be connected to it.

+The first step in defining a dataflow link is to obtain port objects using one of the methods described above.

-Data link
-++++++++++++++++++++++++++++
-A data link is defined as being a dataflow link using the edAddLink method instead of edAddDFLink.  
-The same example as above with a data link::
+Most of the time, when you need a dataflow link between two ports, you also need a control link between the nodes
+of the ports. In this case you can use the method edAddDFLink::
 
   pout=n3.getOutputPort("p1")
   pin=n4.getInputPort("p1")
-  p.edAddLink(pout,pin)
+  p.edAddDFLink(pout,pin)
+
+edAddDFLink is equivalent to edAddCFLink followed by edAddLink.
