get all downstream jobs

[justine....@gmail.com]

I'm working with Build Flow Plugin. What I'm trying to achieve is getting list of all jobs and their numbers triggered by BuildFlow job. I can not find any method in BuildFlow class that returns such a list. Since now i can get object of Flow run class:
def bfJob = Jenkins.getInstance().getItemByFullName("BuildFlowJob").getBuildByNumber(10)
But what to do next? When I call:
bfJob.getJobsGraph()
I see all downstream jobs and edges and etc., I'm shure that there is a better method than than converting it to string and parsing.
Any help will be appreciated.
