=head1 NAME
NetSNMP::OID - Perl extension for manipulating OIDs
=head1 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()
=head1 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 (<, >, ==, ...) 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.
=head2 EXPORT
int snmp_oid_compare(oid1, oid2)
int compare(oid1, oid2)
