Description copied from interface: Request

Gets the number of sub-requests in this request. For GETBULK requests this number may increase over time.

Returns:

a positive integer (greater or equal to zero).

getInitiatingEvent

public org.snmp4j.CommandResponderEvent getInitiatingEvent()

Returns:

getResponse()

getResponse

public org.snmp4j.PDU getResponse()

Description copied from interface: Request

Returns the response object for this request.

Specified by:

getResponse in interface Request<org.snmp4j.CommandResponderEvent,org.snmp4j.PDU,SnmpRequest.SnmpSubRequest>

Overrides:

getResponse in class AbstractRequest<SnmpRequest.SnmpSubRequest,org.snmp4j.CommandResponderEvent,org.snmp4j.PDU>

Returns:

an object containing the response for this request.

iterator

public Iterator<SnmpRequest.SnmpSubRequest> iterator()

iterator

Returns:

Iterator

is2PC

protected boolean is2PC()

getContext

public org.snmp4j.smi.OctetString getContext()

Description copied from interface: Request

Gets the context of the request.

Returns:

an OctetString instance.

getViewName

public org.snmp4j.smi.OctetString getViewName()

setViewName

public void setViewName(org.snmp4j.smi.OctetString viewName)

getSecurityLevel

public int getSecurityLevel()

getSecurityModel

public int getSecurityModel()

getSecurityName

public org.snmp4j.smi.OctetString getSecurityName()

getViewType

public int getViewType()

getViewType

public static int getViewType(int pduType)

Returns the VACM view type for the supplied PDU type.

Parameters:

pduType - a PDU type.

Returns:

the corresponding VACM view type.

public int getRepeaterCount()

isPhaseComplete

public boolean isPhaseComplete()

Description copied from interface: Request

Checks whether the current phase is complete.

Returns:

true if all required processing has been finished for the current request phase. For single phase request types this method returns the same result as Request.isComplete().

isBulkRequest

public boolean isBulkRequest()

Specified by:

isBulkRequest in class AbstractRequest<SnmpRequest.SnmpSubRequest,org.snmp4j.CommandResponderEvent,org.snmp4j.PDU>

getProcessingUserObject

public Object getProcessingUserObject(Object key)

Description copied from interface: Request

Gets the processing user object for the specified key. By default there is no such object associated with a request, but ManagedObjects may put their own objects into the request (for example to avoid unnecessary updates on behalf of the same request).

Parameters:

key - an Object.

Returns:

the associated Object or null if their exists no such association.

setProcessingUserObject

public Object setProcessingUserObject(Object key,
                                      Object value)

Description copied from interface: Request

Sets an user object association.

Parameters:

key - a key Object.

value - a value Object associated with key.

Returns:

the previous value associated with key or null if no such association existed.
