SNMP4J bulkwalk on if-mib

Question

I am using snmp4j.jar. I want to do a snmpwalk on if-table to get ifDescr from all the rows. Using netsnmp : snmpwalk -v2c -c**** -t 1 1.2.3.4 ifDescr I can get ...

IF-MIB::ifDescr.1 = STRING: ATM0

IF-MIB::ifDescr.2 = STRING: Ethernet0
....

I want to do the same with using snmp4j. Any idea how to do that? I followed some tutorial but I am not clear exactly what to do.

Here is the snippet of the code . Hope it help someone .

public Map<String, InterfaceInfoObject> getTableAsStrings(OID[] oids, String communityString) {
        TableUtils tUtils = new TableUtils(snmp, new DefaultPDUFactory());
        List<TableEvent> events = tUtils.getTable(getTarget(), oids, null, null);
        Map<String,InterfaceInfoObject> indexMap = new LinkedHashMap<String,InterfaceInfoObject>();
        for (TableEvent event : events) {
            if(event.isError()) { 
                throw new RuntimeException(event.getErrorMessage());
            }
            for(VariableBinding vb: event.getColumns()) {
                InterfaceInfoObject infterfaceInfo = new InterfaceInfoObject();
                String oid = vb.getOid().toString();
                String index = event.getIndex().toString();
                String colValue = vb.getVariable().toString();
                    if(indexMap.containsKey(index)){
                        getInferfaceObjectAndsetValues(indexMap, oid, index, colValue);
                    }else{
                        putInferfaceInfoObjInMap(indexMap, infterfaceInfo, oid, index,
                                colValue);
                    }
            }
        }
        return indexMap;
