    setEdgeData in interface Graph<CfgNode<?>,CfgEdge,CfgTransformer>
  - toString
```
public String toString()

  - transform
```
public boolean transform(CfgNode<?> node,
                         CfgTransformer actualizer)
```
    Transforms the node with transformer. This will be called by solver to apply optimizations.
    
    Specified by:
    
    transform in interface Graph<CfgNode<?>,CfgEdge,CfgTransformer>
    
    Returns:
    
    true if there were changes made by transformer. While transformation should be always sound, it might be impossible to apply it in current context due to complexities of underlying structures. E.g. it is impossible to delete if statement test expression, while it is not evaluated if statement is not reachable. In this case transformer can return false and do no changes.
