Examples of sun.management.snmp.util.SnmpTableHandler

sun.management.snmp.util.SnmpTableHandler
Defines the interface implemented by an object that holds table data.

        try {
            if (dbg) log.debug("getNextOid", "previous=" + oid);


            // Get the data handler.
            //
            SnmpTableHandler handler = getHandler(userData);
            if (handler == null) {
                // This should never happen.
                // If we get here it's a bug.
                //
                if (dbg) log.debug("getNextOid", "handler is null!");
