Class com.sun.jaw.snmp.manager.SnmpTrapAgent 

java.lang.Object
   |
   +----com.sun.jaw.snmp.manager.SnmpTrapAgent
public class SnmpTrapAgent
extends Object
implements Runnable
The SnmpTrapAgent class implements an SNMP trap dispatcher.

Listener objects can be registered in an SnmpTrapAgent. The SnmpTrapAgent listens for any incoming trap: each time it receives a trap, it inform all the listeners. By default the dispatcher listens to the UDP port 162.

The SnmpTrapAgent class implements Runnable: it is expected to be used as a Thread object.

An SnmpTrapAgent object maintains two lists of listener objects:

An object may implement both interfaces and register itself in both lists: like this, it will receive both versions of traps.

SnmpTrapListener, SnmpV2TrapListener

Constructor Index

o SnmpTrapAgent()
Initializes an SnmpTrapAgent which listens on the port 162.
o SnmpTrapAgent(int)
Initializes an SnmpTrapAgent which listens on the specified port.

Method Index

o addV2TrapListener(SnmpV2TrapListener)
Add an V2 trap listener to this SnmpTrapAgent.
o containsTrapReceiver(SnmpTrapListener)
Returns true if the specified object is listening to V1 traps.
o containsV2TrapReceiver(SnmpV2TrapListener)

Constructors

o SnmpTrapAgent 
 public SnmpTrapAgent() throws SocketException, SnmpStatusException
Initializes an SnmpTrapAgent which listens on the port 162. This constructor invokes SnmpMain.initializeSNMP.

Throws: SocketException
if the object cannot bind of the port 162.
Throws: SnmpStatusException
if initializeSNMP failed.
o SnmpTrapAgent 
 public SnmpTrapAgent(int portNumber) throws SocketException, SnmpStatusException
Initializes an SnmpTrapAgent which listens on the specified port. This constructor invokes SnmpMain.initializeSNMP.

Throws: SocketException
if the object cannot bind of the specified port.
Throws: SnmpStatusException
if initializeSNMP failed.

Methods

o run 
 public void run()
Dispatching loop. This method waits for a trap to be received, select a list of listeners according the version of the trap and activate each listener in the list.

This method is normally called by Thread.start.

o addTrapListener 
 public void addTrapListener(SnmpTrapListener handler)
Add an V1 trap listener to this SnmpTrapAgent.

Parameters:
handler - the listener.
o addV2TrapListener 
 public void addV2TrapListener(SnmpV2TrapListener handler)
Add an V2 trap listener to this SnmpTrapAgent.

Parameters:
handler - the listener.
o containsTrapReceiver 
 public boolean containsTrapReceiver(SnmpTrapListener handler)
Returns true if the specified object is listening to V1 traps.

Parameters:
handler - a listener.
o containsV2TrapReceiver 
 public boolean containsV2TrapReceiver(SnmpV2TrapListener handler)
Returns true if the specified object is listening to V2 traps.

Parameters:
handler - a listener.
o removeTrapListener 
 public void removeTrapListener(SnmpTrapListener handler)
Remove a V1 trap listener.

Parameters:
the - listener to be removed.
o removeV2TrapListener 
 public void removeV2TrapListener(SnmpV2TrapListener handler)
Remove a V2 trap listener.

Parameters:
the - listener to be removed.
o getTrapListeners 
 public Enumeration getTrapListeners()
Get all of the V1 trap listeners.

Returns:
an Enumeration of SnmpTrapListener objects
o getV2TrapListeners 
 public Enumeration getV2TrapListeners()
Get all of the V2 trap listeners.

Returns:
an Enumeration of SnmpV2TrapListener objects
o getPduFactory 
 public SnmpPduFactoryIf getPduFactory()
Get the PDU factory associated to this SnmpTrapAgent.

Returns:
the PDU factory (always non-null)
o setPduFactory 
 public void setPduFactory(SnmpPduFactoryIf factory)
Set the PDU factory associated to this SnmpTrapAgent.

Parameters:
factory - the PDU factory (if null, the default factory is set)
