Direct Known Subclasses:

ConditionalPDGNode, LoopedPDGNode
```
public class PDGNode
extends Object
```
This class defines a Node in the Program Dependence Graph. There might be a need to store additional information in the PDG nodes. In essence, the PDG nodes represent (within them) either CFG nodes or Region nodes.
