=head1 NAME

Net::ISC::DHCPd::Config::FailoverPeer - Failover Peer Configuration

=head1 DESCRIPTION

See L<Net::ISC::DHCPd::Config::Role> for methods and attributes without
documentation.

An instance from this class, comes from / will produce the block below:

    $name_attribute_value $value_attribute_value;

    failover peer "$name" {
        $primary;
        address dhcp-primary.example.com;
        port 519;
        peer address dhcp-secondary.example.com;
        peer port 520;
        max-response-delay 60;
        max-unacked-updates 10;
        mclt 3600;
        split 128;
        load balance max seconds 3;
    }

=head1 METHODS

=head2 slurp

This method is used by L<Net::ISC::DHCPd::Config::Role/parse>, and will
slurp the content of the function, instead of trying to parse the
statements.

=cut

sub slurp {
    my($self, $line) = @_;

    while(my ($name, $value) = each (%{$self->arguments})) {
        my $regex = $value->{regex};
        if ($line =~ $regex) {
            $self->$name($1);
            push(@{$self->_order}, $name);
        }
    }

    return 'last' if($line =~ /^\s*}/);
    return 'next';
}

=head2 captured_to_args

See L<Net::ISC::DHCPd::Config::Role/captured_to_args>.

=cut

sub captured_to_args {
    return { name => $_[1] }; # $_[0] == quote or empty string
}

=head2 generate

See L<Net::ISC::DHCPd::Config::Role/generate>.

=cut

sub generate {
    my $self = shift;

    my $return = sprintf('failover peer "%s" {', $self->name);
    $return .= "\n";

    for(@{$self->_order}) {
        $return .= sprintf('    '. $self->arguments->{$_}->{text} . ";\n", $self->$_);
    }

    $return .= "}\n";

    return($return);
