Constructor Details

ReverseDepthFirstSearch

public ReverseDepthFirstSearch(CFG cfg)

Constructor.

Parameters:

cfg - the CFG to perform the reverse depth first search on

Method Details

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
