public class SnmpGetTable
extends Object

Variable Index

o context
The SNMP context used to access the node which owns this instance
o dc
The parent DataCollector
o elementCount
The number of elements in this object
o endOfTable
Flag used to indicate when we hit the end of the requested OID prefix
o initialOid
The original OID requested
o lastOid
The last OID we requested in the SNMP GETNEXT packet
o pdu
The SNMP GETNEXT PDU used to iterate over the OID table
o values
The list of values for this SNMP GETNEXT object
o waiting

Constructor Index

o SnmpGetTable(SnmpContext, String, String, DataCollector)
Constructor.

Method Index

o elementAt(int)
Returns the Nth element in the SNMP table.
o size()
Return the size of the SNMP table.
o update(Observable, Object)
This method is called via notify() by the underlying SNMP code when a response is received.

Variables

o values 
 private Vector values
The list of values for this SNMP GETNEXT object

o elementCount 
 private int elementCount
The number of elements in this object

o initialOid 
 private String initialOid
The original OID requested

o lastOid 
 private String lastOid
The last OID we requested in the SNMP GETNEXT packet

o context 
 private SnmpContext context
The SNMP context used to access the node which owns this instance

o endOfTable 
 private boolean endOfTable
Flag used to indicate when we hit the end of the requested OID prefix

o waiting 
 private boolean waiting
Flag used to indicate that we are waiting the the GETNEXT reply

o pdu 
 private OneGetNextPdu pdu
The SNMP GETNEXT PDU used to iterate over the OID table

o dc 
 private DataCollector dc
The parent DataCollector

Constructors

o SnmpGetTable 
 public SnmpGetTable(SnmpContext context,
                     String comm,
                     String var,
                     DataCollector dc)
Constructor.

Parameters:
context - The SNMP context for this request
comm - The SNMP community name to use when sending this GETNEXT
var - The SNMP ObjectID to GETNEXT
dc - pointer to parent DataCollector

Methods

o size 
 public int size()
Return the size of the SNMP table.

o elementAt 
 public Object elementAt(int idx)
Returns the Nth element in the SNMP table.

Parameters:
idx - The index of the desired table element.
Returns:
the object which represents the value at the idx'th entry
o update 
 public void update(Observable ovs,
                    Object obj)
This method is called via notify() by the underlying SNMP code when a response is received. Store the answer in the form of a Varbind entry in a local Vector table 'values'.
