4.3.5 MDagMessage

The following MDagMessage methods differ from their C++ counterparts.

addDagCallback2( [node,] msgType, func, clientData=None, status=None)
In the C++ API there are four overloads of the addDagCallback() method. Two of them register a callback that just takes the child node, the parent node and the client data as input whereas the other two register a callback that receives the DAG message as well. In this Python binding these two groups are split into two methods. The addDagCallback() method registers the callback that receives the message whereas addDagCallback2() registers the callback without the message argument.
