Abstract Value Members

  1. abstract def getPeerExecutorId: Long

    Get a long representing the executorId for the peer of this connection.

    Get a long representing the executorId for the peer of this connection.

    returns

    the executorId as a long

  2. abstract def registerReceiveHandler(messageType: MessageType.Value): Unit

    Register interest in messages of messageType.

    Register interest in messages of messageType.

    Note

    Currently MessageType.Buffer is the only supported message type.

  3. abstract def request(messageType: MessageType.Value, request: ByteBuffer, cb: TransactionCallback): Transaction

    This performs a request/response for a message of type MessageType.

    This performs a request/response for a message of type MessageType. The response Transaction on completion will call the callback (cb). The caller of request must close, or consume the response in the transaction, otherwise we can leak.

    messageType

    value of the MessageType enum

    request

    the populated request direct buffer ByteBuffer

    cb

    callback to handle transaction status. If successful the memory described using "response" will hold the response as expected, otherwise its contents are not defined.

    returns

    a transaction representing the request
