    • Method Detail

      • receiveMessages

        void receiveMessages()
        Called by our framework, to deserialize the messages from c++ to java. Must be called before getMessages

      • getMessages

        Iterable<IN_MSG_T> getMessages​(long lid)
        Get the messages received from last round.
        Parameters:
        lid - local id.
        Returns:
        received msg.

      • messageAvailable

        boolean messageAvailable​(long lid)
        Check any message available on this vertex.
        Parameters:
        lid - local id
        Returns:
        true if received messages.

      • sendMessage

        void sendMessage​(OID_T dstOid,
                 OUT_MSG_T message)
        Send one message to dstOid.
        Parameters:
        dstOid - vertex to receive this message.
        message - message.

      • sendMessageToAllEdges

        void sendMessageToAllEdges​(org.apache.giraph.graph.Vertex<OID_T,​VDATA_T,​EDATA_T> vertex,
                           OUT_MSG_T message)
        Send msg to all neighbors of vertex.
        Parameters:
        vertex - querying vertex
        message - message to send.

      • finishMessageSending

        void finishMessageSending()
        Make sure all messages has been sent.

      • anyMessageReceived

        boolean anyMessageReceived()
        Check any messages received. For mpi-based message manager, we check any message to self produced. For netty-based message manager, we check any message received.
        Returns:
        true if any message received.
