NetSNMP::OID - Perl extension for manipulating OIDs

# [SYNOPSIS](#SYNOPSIS)

```
  use NetSNMP::OID;
  my $oid = new NetSNMP::OID('sysContact.0');
  if ($oid < new NetSNMP::OID('ifTable')) {
      do_something();
  }
  my @numarray = $oid->to_array();
  # appending oids
  $oid = new NetSNMP::OID('.1.3');
  $oid += ".6.1";
  # -> .1.3.6.1
  # appending index strings
  $oid2 = $oid + "\"wes\"";
  # -> .1.3.6.1.3.119.101.115
  $oid3 = $oid + "\'wes\'";
  # -> .1.3.6.1.119.101.115
  $len = $oid3->length();
  # -> 7
  # retrieving indexes from an oid:
  $arrayref = $tableoid->get_indexes()
```

# [DESCRIPTION](#DESCRIPTION)

The NetSNMP::OID module is a simple wrapper around a C-based net-snmp oid (which is an array of unsigned integers). The OID is internally stored as a C array of integers for speed purposes when doing comparisons, etc.

The standard logical expression operators (&lt;, &gt;, ==, ...) are overloaded such that lexographical comparisons may be done with them.

The + operator is overloaded to allow you to append stuff on to the end of a OID, like index segments of a table, for example.

## [EXPORT](#EXPORT)

int snmp\_oid\_compare(oid1, oid2) int compare(oid1, oid2)
