public void responseReceived()

getNextPDU

public PDU getNextPDU()

setNextPDU

public void setNextPDU(PDU nextPDU)

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

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:

run in interface Runnable

Specified by:

run in class TimerTask

setFinished

public boolean setFinished()

setMaxRequestStatus

public void setMaxRequestStatus(int maxRequestStatus)

getMaxRequestStatus

public int getMaxRequestStatus()

isResponseReceived

public boolean isResponseReceived()

getDurationNanos

public long getDurationNanos()

Gets the nanoseconds waited for a response for this pending request.

Returns:

a value greater than 0 represents the nanoseconds Snmp waited until a response was received.

Since:

3.7.5

cancel

public boolean cancel()

Cancels the request and clears all internal fields by setting them to null.

Overrides:

cancel in class TimerTask

Returns:

true if cancellation was successful.
