      • isValidWFNet

        public static boolean isValidWFNet​(Petrinet net)
        This method checks whether: 1) There is exactly one input place, 2) there is exactly one output place, 3) all nodes are on a path from the input place to the output place.
        Parameters:
        net - the net to be checked for being a valid WF net
        Returns:
        true if the net is a valid WF net (Has nothing to do with soundness)

      • getInputPlace

        public static Place getInputPlace​(Petrinet net)
        Returns the input place of this net. Note that it is assumed that isValidWFNet(net)==true. If not, the result is unpredictable.
        Parameters:
        net - the net of which the input place is requested
        Returns:
        the input place if isValidWFNet(net)==true. Garbage otherwise (potentially null)

      • getOutputPlace

        public static Place getOutputPlace​(Petrinet net)
        Returns the output place of this net. Note that it is assumed that isValidWFNet(net)==true. If not, the result is unpredictable.
        Parameters:
        net - the net of which the output place is requested
        Returns:
        the output place if isValidWFNet(net)==true. Garbage otherwise (potentially null)

      • getSourcePlaces

        public static java.util.SortedSet<Place> getSourcePlaces​(Petrinet net)
        Returns the set of source places of this net.
        Parameters:
        net - the net of which the set of source places is requested
        Returns:
        the set of source places.

      • getSinkPlaces

        public static java.util.SortedSet<Place> getSinkPlaces​(Petrinet net)
        Returns the set of sink places of this net.
        Parameters:
        net - the net of which the set of sink places is requested
        Returns:
        the set of sink places.

      • getUnconnectedNodes

        public static java.util.SortedSet<PetrinetNode> getUnconnectedNodes​(Petrinet net)
        Returns the set of unconnected nodes of this net.
        Parameters:
        net - the net of which the set of unconnected nodes is requested
        Returns:
        the set of unconnected nodes.

      • shortCircuit

        public static java.lang.Object[] shortCircuit​(org.processmining.framework.plugin.PluginContext context,
                                              Petrinet net)
