  • Field Details

  • Constructor Details

    • GraphWriter

      private GraphWriter(IvmlGraphMapper.IvmlGraph graph)
      Creates a writer for graph.
      Parameters:
      graph - the graph to write

  • Method Details

    • mapNodes

      private void mapNodes()
      Maps the nodes of graph to ids.

    • serviceToData

      private void serviceToData(net.ssehub.easy.varModel.confModel.IDecisionVariable service, org.json.simple.JSONObject data)
      Turns service information into data for the editor.
      Parameters:
      service - the IVML variable representing the service, may be null
      data - the data object to be modified

    • processBackward

      private void processBackward(net.ssehub.easy.varModel.confModel.IDecisionVariable set, org.json.simple.JSONObject data, String name)
      Processes backward flows by adding their type names as String array into a JSON field called name.
      Parameters:
      set - denotes the type set (input/output) to be analyzed
      data - the data object to be modified
      name - the name of the field to write the backward flows into

    • writeHomeData

      private org.json.simple.JSONObject writeHomeData()
      Writes the "home" data section.
      Returns:
      the home data JSON object

    • getId

      private String getId(IvmlGraphMapper.IvmlGraphNode node, String dflt)
      Returns the ID of the node in terms of its IVML variable name.
      Parameters:
      node - the node
      dflt - the default value
      Returns:
      the node ID

    • writeGraph

      private String writeGraph()
      Writes the graph to a JSON string.
      Returns:
      the JSON string

    • writeEdges

      private org.json.simple.JSONObject writeEdges(IvmlGraphMapper.IvmlGraphNode node, Iterable<? extends IvmlGraphMapper.IvmlGraphEdge> edges, boolean inputEdges)
      Writes the given edges.
      Parameters:
      node - the start/end node defining the edges
      edges - the edges to write
      inputEdges - are we writing input or output edges
      Returns:
      the edges as JSON object

    • collectForwardTypes

      private void collectForwardTypes(IvmlGraphMapper.IvmlGraphNode start, IvmlGraphMapper.IvmlGraphNode end, IvmlGraphMapper.IvmlGraphEdge edge, org.json.simple.JSONObject data)
      Collects common forward types between the nodes involved in edge and adds the results as "type"-array to data.
      Parameters:
      start - the start node
      end - the end node
      edge - the edge (for future information)
      data - the data object to add a "types" field

    • collectTypes

      private void collectTypes(net.ssehub.easy.varModel.confModel.IDecisionVariable set, Predicate<Boolean> direction, Consumer<String> consumer)
      Collects IIP-Ecosphere data types.
      Parameters:
      set - the set of decisions to process
      direction - a directional predicate over forward/backward types
      consumer - processes identified type names

    • nextCount

      private int nextCount(IvmlGraphMapper.IvmlGraphNode node, Map<IvmlGraphMapper.IvmlGraphNode,Integer> counts)
      Returns the next input/output count for node with respect to the counting map counts. A call will modify counts as a side effect on the entry for node, either setting it to 1 or incrementing it by one.
      Parameters:
      node - the note to return the count for
      counts - the counting map to use
      Returns:
      the counter
