      Set<NESTWorkflowObject> extractTaskSequences(int minLength)
      Extracts each longest sequence of task nodes without controlflow nodes and with at least minLength tasks
      Parameters:
      minLength - minimum number of tasks in a sequence
      Returns:
      set of nest workflow graphs with task sequences

    • extractSingleTaskBlocks

      Set<NESTWorkflowObject> extractSingleTaskBlocks()
      Returns a set of nest workflow graphs where each graph contains a single task node from the given workflow graph.
      Returns:
