Class DefaultCounterListener

java.lang.Object

org.snmp4j.mp.DefaultCounterListener

All Implemented Interfaces:

EventListener, CounterListener

public class DefaultCounterListener
extends Object
implements CounterListener

The DefaultCounterListener is the default implementation of the CounterListener interface. For any counter incrementation event it checks whether the referenced counter object already exists. If not, it will be created and initialized with one. Otherwise, the current value will be incremented by one. In either case, the current value will be returned in the event object.

To use a DefaultCounterListener with SNMP4J, add it to the default CounterSupport by:

   CounterSupport.getInstance().addCounterListener(new DefaultCounterListener());
