How to use

getTopologicalIterator

method

in

cascading.flow.planner.process.FlowNodeGraph

private void printFlowStep() {
  Iterator<FlowNode> iterator = getFlowNodeGraph().getTopologicalIterator();
  LOG.info("Step Cnt: {} ", getFlowNodeGraph().vertexSet().size());
  LOG.info("Edge Cnt: {} ", getFlowNodeGraph().edgeSet().size());
  LOG.info("Src Set: {} ", getFlowNodeGraph().getSourceElements());
  LOG.info("Snk Set: {} ", getFlowNodeGraph().getSinkElements());
  LOG.info("##############");
  while(iterator.hasNext()) {
    FlowNode next = iterator.next();
    LOG.info("Node cnt: {} ", next.getElementGraph().vertexSet().size());
    LOG.info("Edge cnt: {} ", next.getElementGraph().edgeSet().size());
    LOG.info("Nodes: {} ", next.getElementGraph().vertexSet());
    LOG.info("-----------");
  }
}

Iterator<FlowNode> iterator = flowNodeGraph.getTopologicalIterator();

Iterator<FlowNode> iterator = getFlowNodeGraph().getTopologicalIterator();

Iterator<FlowNode> iterator = getFlowNodeGraph().getTopologicalIterator();
