        The activity, or null if it does not exist.

      • getNumberOfNodes

        int getNumberOfNodes()
        Returns:
        The number of nodes in the model.

      • getAllNodeNames

        java.lang.String[] getAllNodeNames()
        Returns:
        The added node names, in the order they were added.

      • getNodeIndices

        java.lang.Iterable<java.lang.Integer> getNodeIndices()

      • getIndicesOfNodeName

        gnu.trove.set.TIntSet getIndicesOfNodeName​(java.lang.String nodeName)
        Parameters:
        nodeName -
        Returns:
        The indices of the nodeName.

      • addNode

        int addNode​(java.lang.String nodeName)
        Inserts an activity.
        Parameters:
        nodeName -
        Returns:
        the index of the newly added node.

      • addNodes

        void addNodes​(java.lang.String[] nodeNames)
        Adds an array of nodes with the provided names. Typically more efficient than adding the nodes one-by-one.
        Parameters:
        nodeNames -

      • isEmptyTraces

        boolean isEmptyTraces()
        Returns:
        Whether the model supports empty (epsilon) traces.

      • setEmptyTraces

        void setEmptyTraces​(boolean emptyTraces)
        Set whether the model supports empty (epsilon) traces.
        Parameters:
        emptyTraces -

      • addEdge

        void addEdge​(int sourceIndex,
             int targetIndex)
        Adds an edge. Has no effect if the edge was already present.
        Parameters:
        sourceIndex -
        targetIndex -

      • removeEdge

        void removeEdge​(int sourceIndex,
                int targetIndex)
        Removes an edge. Has no effect if the edge was not present.
        Parameters:
        sourceIndex -
        targetIndex -

      • getEdges

        java.lang.Iterable<java.lang.Long> getEdges()
        Gives an iterable that iterates over all edges; The edges that are returned are indices. The iterable supports remove() calls, however calls to this method might invalidate other iterables.
        Returns:

      • containsEdge

        boolean containsEdge​(int sourceIndex,
                     int targetIndex)
        Returns whether the graph contains an edge between source and target.
        Parameters:
        sourceIndex -
        targetIndex -
        Returns:

      • getEdgeSource

        int getEdgeSource​(long edgeIndex)
        Returns the node the edgeIndex comes from.
        Parameters:
        edgeIndex -
        Returns:

      • getEdgeTarget

        int getEdgeTarget​(long edgeIndex)
        Returns the node the edgeIndex points to.
        Parameters:
        edgeIndex -
        Returns:

      • hasStartNodes

        boolean hasStartNodes()

      • addStartNode

        void addStartNode​(int nodeIndex)
        Has no effect if the activity was already a start node.
        Parameters:
        nodeIndex -

      • getStartNodes

        gnu.trove.set.TIntSet getStartNodes()

      • getNumberOfStartNodes

      • addEndNode

        void addEndNode​(int nodeIndex)
