      • ConnectedGraphServer

        @Inject
public ConnectedGraphServer​(org.opendaylight.mdsal.binding.api.DataBroker dataBroker)

    • Method Detail

      • close

        @PreDestroy
public void close()
        Remove the Operation Graph Model and destroy the transaction chain.
        Specified by:
        close in interface AutoCloseable

      • resetTransactionChain

        protected void resetTransactionChain()
        Reset the transaction chain only so that the PingPong transaction chain will become usable again. However, there will be data loss if we do not apply the previous failed transaction again

      • clearGraph

        public void clearGraph​(Graph graph)
        Clear Graph. This method is used by the Connected Graph to clear associated Graph.
        Parameters:
        graph - Graph associated to the Connected Graph

      • addVertex

        public void addVertex​(Graph graph,
                      Vertex vertex,
                      Vertex old)
        Add Vertex to existing Graph. Old vertex is remove first. This method is called when a Connected Vertex is created (See addVertex() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the vertex will be stored
        vertex - Vertex to be inserted in the graph
        old - Old vertex when performing an update. Must be null for a simple addition

      • deleteVertex

        public void deleteVertex​(Graph graph,
                         Vertex vertex)
        Remove Vertex to existing Graph. This method is called when a Connected Vertex is removed (See deleteVertex() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the vertex is stored
        vertex - Vertex to be removed

      • addEdge

        public void addEdge​(Graph graph,
                    Edge edge,
                    Edge old)
        Add Edge to existing Graph. Old edge is remove first. This method is called when a Connected Edge is created (See addEdge() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the edge will be stored
        edge - Edge to be inserted in the graph
        old - Old edge when performing an update. Must be null for a simple addition

      • deleteEdge

        public void deleteEdge​(Graph graph,
                       Edge edge)
        Remove Edge to existing Graph. This method is called when a Connected Edge is removed (See deleteEdge() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the edge is stored
        edge - Edge to be removed

      • addPrefix

        public void addPrefix​(Graph graph,
                      Prefix prefix)
        Add Prefix to existing Graph. This method is called when a Prefix is added to a Connected Vertex (See addPrefix() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the prefix will be stored
        prefix - Prefix to be interted in the graph

      • deletePrefix

        public void deletePrefix​(Graph graph,
                         Prefix prefix)
        Remove Prefix to existing Graph. This method is called when a Prefix is removed from a Connected Vertex (See deletePrefix() method from ConnectedGraph Interface).
        Parameters:
        graph - Graph where the prefix is stored
        prefix - Prefix to be removed

      • onTransactionChainFailed
