    • pduHandleAssigned

      public void pduHandleAssigned(PduHandle handle, PDU pdu)
      Description copied from interface: PduHandleCallback
      A new PduHandle has been created for a PDU. This event callback notification can be used to get informed about a new PduHandle (just) before a PDU has been sent out.
      Specified by:
      pduHandleAssigned in interface PduHandleCallback<A extends Address>
      Parameters:
      handle - a PduHandle instance that uniquely identifies a request - thus in most cases the request ID.
      pdu - the request PDU for which the handle has been created.

    • run

      public void run()
      Process retries of a pending request.
      Specified by:

    • isResponseReceived

      public boolean isResponseReceived()

    • cancel

      public boolean cancel()
      Cancels the request and clears all internal fields by setting them to null.
      Overrides:
      cancel in class TimerTask
