[SNMP4J] Creating index for adding row to table entry

[Frank Fock]

Hi Pradip,

The toSubIndex(..) methods of the SMI types
are used to form an index OID from SNMP values.
It does *not* hash the values. It simply
transforms them. For OctetStrings, it uses each
characters decimal value as OID sub-identifier.

To generate a integer index, you can use:

IndexGenerator ig = new IndexGenerator(new Integer32(0));
OID nextIndex = ig.nextSubIndex();

Regards,
Frank
