java.lang.Object
  com.adventnet.adaptors.snmp.SNMPEnableTable

All Implemented Interfaces:

com.adventnet.utils.jmx.JmxTableModelListener, javax.management.MBeanRegistration

public class SNMPEnableTable
extends java.lang.Object
implements com.adventnet.utils.jmx.JmxTableModelListener, javax.management.MBeanRegistration

This class acts as the Managed Resource of the RequiredModelMBean. For each TableMBean ,that is deployed in the cluster server, an instance of this class is created and is registered in the admin MBean server. This MBean gives a consolidated view of the data present in the cluster MBeans.
