=head1 NAME

Data::ICal::Entry::Alarm::None - Represents an default no-op alarm

=head1 SYNOPSIS

    my $valarm = Data::ICal::Entry::Alarm::None->new();
    $vevent->add_entry($valarm);

=head1 DESCRIPTION

A L<Data::ICal::Entry::Alarm::None> object represents a default alarm
that does nothing; this is different from a lack of alarm, because
clients may be expected to "override" any default alarm present in
calendar data with the current value retrieved from the server.  This
class is a subclass of L<Data::ICal::Entry::Alarm> and accepts all of
its methods.

This element is not included in the official iCal RFC, but is rather an
unaccepted draft standard; see
L<https://tools.ietf.org/html/draft-daboo-valarm-extensions-04#section-11>
B<Its interoperability and support is thus limited.> This is alarm type
is primarily used by Apple.
