Returns the immediate dominator of a cfgNode. The returned value can be None if cfgNode was the cfg entry node while calculating the dominator relation or if cfgNode is dead code. In the post dominator case "dead code" means code which does lead to the normal method exit. An example would be a thrown excpetion.
