public class NotificationAdaptor

extends java.lang.Object

implements TrapListener

This class is an SNMP NotificationAdaptor for use with SnmpTrapReceiver. It supports event generation per the JDK 1.1 event model.

To use in an application, simply instantiate an SnmpTrapReceiver, specify the port, and register instance of this to receive traps. The purpose of this adaptor is to convert a v2 trap pdu to v1 trap pdu. For example,

    SnmpTrapReceiver receiver = new SnmpTrapReceiver();
    receiver.setPort(162);

    NotificationAdaptor filter = new NotificationAdaptor();
    receiver.addTrapListener(filter);
    TrapListener listener = new TrapListener() {
        public void receivedTrap(TrapEvent trap) {
            System.err.println("Got a trap from: "+trap.getRemoteHost());
        }
    };
    

    filter.addTrapListener(listener);
  

Supply the applet in the constructor if using applets and may need to use SAS.

Method Detail

receivedTrap

public void receivedTrap(TrapEvent evt)

Fires the received trap event after applying this filter to the registered listeners.

Specified by:

receivedTrap in interface TrapListener

addTrapListener

public void addTrapListener(TrapListener l)

Add a listener for events from this target. The listener listens for events from any or all SNMP requests.

removeTrapListener

public void removeTrapListener(TrapListener l)

Remove a listener for events from this target.

convertTrap

protected TrapEvent convertTrap(TrapEvent trp)

Attempts to convert v2c notification pdu parameters to v1 trap pdu parameters. Returns new pdu if successful. Otherwise returns the old pdu.

compare

boolean compare(int[] a,
                int[] b,
                int len)
