IRegion (Soot - a J*va Optimization Framework 4.6.0 API)

All Known Implementing Classes:

PDGRegion, Region
```
public interface IRegion
```
This interface represents a region of control dependence in the control flow graph. There are different kinds of region representations that may slightly differ in definition or implementation; here is an interface that is expected to be supported by all these different regions.
