public interface NESTControlflowNodeObject extends NESTSequenceNodeObject
Interface of a Controlflow-Node of a NEST-graph. Each control flow element in a workflow, such as split/join elements for and/xor blocks, are represented as a control-flow node. The semantic description of a control flow node specifies which control flow element is represented. Data-centric workflows may have no control flow nodes.

  • Method Details

    • isStartControlflowNode

      boolean isStartControlflowNode()
      Checks if the controlflow node is a start node (AND-split, XOR-split, LOOP-join).
      Returns:
      true if the node is a start node, false otherwise

    • isEndControlflowNode

      boolean isEndControlflowNode()
      Checks if the controlflow node is an end node (AND-join, XOR-join, LOOP-split).
      Returns:
      true if the node is an end node, false otherwise

    • getMatchingBlockControlflowNode

      NESTControlflowNodeObject getMatchingBlockControlflowNode()
      When the controlflow-node is located in a block-oriented controlflow the matching controlflow-node of the controlflow-block is returned.
      Returns:
      matching controlflow-node in a block-oriented controlflow, null otherwise

    • setMatchingBlockControlflowNode

      void setMatchingBlockControlflowNode(NESTControlflowNodeObject matchingBlockControlflowNode)
      Set a controlflow node as the matching block node.
      Parameters:
      matchingBlockControlflowNode - Controlflow node, that should be the matching partner of the current node.

    • getNumberOfNonEmptyBranches

      int getNumberOfNonEmptyBranches()
      Returns the number of branches ignoring direct controlflow edges between start and end controlflow nodes.
      Returns:
      number of non-empty branches

    • getNumberOfBranches

      int getNumberOfBranches()
      Returns the number of branches.
      Returns:
      number of branches

    • isLoopNode

      boolean isLoopNode()
      Returns:

    • isAndNode

      boolean isAndNode()

      Map<NESTSequenceNodeObject,Set<NESTSequenceNodeObject>> getBlockSequencePaths()
      Method to extract a map of possible paths and its elements of a block sequence e.g. a parallel branch contains two (or more) paths

    • getInnerBlockElements

      Set<NESTSequenceNodeObject> getInnerBlockElements()
