```
public DepthFirstSearch(CFG cfg)
```
    Constructor.
    
    Parameters:
    cfg - the CFG to perform the depth first search on
- Method Detail
  - getNextSearchTreeRoot
```
protected BasicBlock getNextSearchTreeRoot()
```
    Description copied from class: AbstractDepthFirstSearch
    
    Choose the next search tree root. By default, this method just scans for a WHITE vertex. Subclasses may override this method in order to choose which vertices are used as search tree roots.
    
    Overrides:
    
    getNextSearchTreeRoot in class AbstractDepthFirstSearch<CFG,Edge,BasicBlock>
    
    Returns:
    the next search tree root
