Net::SNMP::Util::TC - Giving Textual Convention of MIBs

=head1 SYNOPSIS

    use Net::SNMP::Util;
    use Net::SNMP::Util::OID qw(if*);
    use Net::SNMP::Util::TC qw(updown iftype);

    $r = snmpget(
        snmp => { -hostname => $host },
        oids => { map oidp("$_.1"), qw/ifName ifType ifAdminStatus ifOperStatus/ }
    );
    my $tc = Net::SNMP::Util::TC->new();

    printf "port:%s index:%d type:%s astat:%s ostat:%s\n",
        $r->{"ifName.1"}, $index, $tc->ifType($r->{"ifType.1"}),
            updown($r->{"ifAdminStatus.1"}),
            updown($r->{"ifOperStatus.1" });


=head1 DESCRIPTION

Module C gives the way to convert some MIB values to
humans recognizable text.

=head1 EXPORT

This module, C, exports C and C
defalut which are for ifAdminStatus and ifOperStatus to check up or down
simply.

To know status, kind or type fully, make object first and than call method
with MIB value to convert like below;

    $tc = Net::SNMP::Util::TC->new();
    $status = $tc->ifAdminStatus($value);

=head1 FUNCTIONS

=head2 isup()

    isup( $value );

If $value is "1", function returns 1. If values else this returns 0.

=head2 updown()

    updown( $value );

If $value is "1", function returns string 'up'. Else returns 'down'.

=cut

# -----------------------------------------------------------------------------
sub isup
{
    my $value = shift || 0;
    return ($value eq "1")? 1: 0;

sub updown

}

=head1 METHODS

=head2 new()

    $tc = Net::SNMP::Util::TC->new();

First creat an object for conversion. No arguments are need for this class.
Then call method, which name is same as MIB name, with passing value you want to
convert. e.g.;

    $type = $tc->ifType( 132 );     # "coffee"

=head2 Avaiable Methods

Textual conversion methods now avaiable are;

=over

=item ifAdminStatus()

For conversion value of MIB ifAdminStatus.

=item ifOperStatus()

For conversion value of MIB ifOperStatus.

=item ifType()

For conversion value of MIB ifType. MIB ifType is now defined as IANAifType.

=item ifRcvAddressType()

For conversion value of MIB ifRcvAddressType.

=item TruthValue()

For conversion value of MIB TruthValue.

=item StorageType()

For conversion value of MIB StorageType.

=back

=cut

sub new {
    my $class = shift;
    bless \eval{ my $s }, $class;

# =============================================================================

=head1 METHODS

=cut

sub AUTOLOAD
{
    my ($self, $value) = @_;
    my $method = our $AUTOLOAD;     # $method = MIB name

    $method =~ s/.*:://o;

    if ( exists $_TC_base{$method} )

        *{$method} = sub {

                return $_TC_base{$method}->{$v};
            } else {

            }
            return undef;
        };
        return $method->($self,$value);
    }
    return undef;
}

sub DESTROY {}

# -----------------------------------------------------------------------------

=head2 TRUE()

This method always returns 1 which is defined as true value in MIB TruthValue
at RFC-1903.

=head2 FALSE()

This method always returns 2 which is defined as false value in MIB TruthValue
at RFC-1903.

=cut

# -----------------------------------------------------------------------------
sub TRUE  { 1 };
sub FALSE { 2 };
