Soot之 遍历Control Flow Graph

当我们获取到一个method的UnitGraph时，可以通过下面方法遍历CFG：

UnitGraph: g

		List ulist = g.getHeads();
		Unit u = ulist.get(0);
		while (!unitBelongList(u, g.getTails()))
		{


			EntityNode eNode = new EntityNode();
			u = g.getSuccsOf(u).get(0);


			Stmt stmt = (Stmt) u;
		}

boolean unitBelongList(Unit u, List g)
{
    for(Unit i:g)
    {
        if(i.equals(u))
                return true;
    }
            return false;
}
