                             java.lang.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

                               java.lang.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

                                              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,

        node - the note to return the count for
        counts - the counting map to use
        Returns:
