public class ProxyForwarderImpl extends java.lang.Object implements ProxyForwarder
TheProxyForwarderImpl
class implements a proxy forwarder instance as defined by RFC 3413. It is configured through the SNMP-PROXY-MIB and SNMP-TARGET-MIB implementations provided on construction. It sends notifications through the provided SNMP session.- Version:

ProxyForwarderImpl
public ProxyForwarderImpl(org.snmp4j.Session session, SnmpProxyMIB proxyMIB, SnmpTargetMIB targetMIB)
Creates aProxyForwarder
implementation based on a SNMP session used to send the notifications and a SNMP-PROXY-MIB and a SNMP-TARGET-MIB implementation used for its configuration.- Parameters:
session
- a SNMP session.proxyMIB
- aSnmpProxyMIB
implementation with the proxy configuration.targetMIB
- aSnmpTargetMIB
implementation with the target configuration.

Method Detail
-
forward
public boolean forward(ProxyForwardRequest request)
Forwards aRequest
if it matches the criteria defined by the SNMP-PROXY-MIB associated with this proxy forwarder.- Specified by:
forward
in interfaceProxyForwarder
- Parameters:
request
- aProxyForwardRequest
encapsuling the forwarding request.- Returns:
true
if the request has been forwarded,false
otherwise.
-
getMatches
protected java.util.List getMatches(ProxyForwardRequest request)
-
matchParameters
protected boolean matchParameters(ProxyForwardRequest request, org.snmp4j.smi.OctetString paramIn)
-
singleForward
protected org.snmp4j.event.ResponseEvent singleForward(ProxyForwardRequest request)
-
proxyBackwardTranslation
protected boolean proxyBackwardTranslation(org.snmp4j.PDU reqPDU, org.snmp4j.PDU pdu, org.snmp4j.event.ResponseEvent response)
-
proxyForwardTranslation
protected void proxyForwardTranslation(ProxyForwardRequest request, org.snmp4j.PDU source, org.snmp4j.PDU target) throws java.lang.IllegalArgumentException
Translates a source PDU into the supplied target PDU. The mapping between the source PDU and the target PDU is done as defined by RFC 3584.- Parameters:
request
- the proxy forwarding request.source
- the source PDU instance.target
- the target PDU instance. The variable bindings of the source will replace any VBs of the target instance. If the source PDU cannot be converted to the target PDUtarget
is not changed. Instead an intermediate PDU is returned.- Throws:
java.lang.IllegalArgumentException
- ifsource
contains an illegal notification PDU.
-
multipleForward
protected boolean multipleForward(ProxyForwardRequest request)
-
addCounterListener
public void addCounterListener(org.snmp4j.event.CounterListener l)
-
removeCounterListener
public void removeCounterListener(org.snmp4j.event.CounterListener l)
-
fireIncrementCounter
protected void fireIncrementCounter(org.snmp4j.event.CounterEvent event)
-
setSession
public void setSession(org.snmp4j.Session snmpSession)
Sets the SNMP session to used by this proxy forwarder for sending SNMP messages.- Parameters:
snmpSession
- the Snmp instance to be used to send SNMP messages.- Since:
- 1.9.1
