NAME

       Data::ICal::Entry::Alarm::Audio - Represents an audio alarm in an iCalendar file

SYNOPSIS

           my $valarm = Data::ICal::Entry::Alarm::Audio->new();
           $valarm->add_properties(
               attach => [ "ftp://host.com/pub/sounds/bell-01.aud", { fmttype => "audio/basic" } ],
               # Dat*e*::ICal is not a typo here
               trigger   => [ Date::ICal->new( epoch => ... )->ical, { value => 'DATE-TIME' } ],
           );

           $vevent->add_entry($valarm);

DESCRIPTION

       A Data::ICal::Entry::Alarm::Audio object represents an audio alarm attached to a todo item
       or event in an iCalendar file.  (Note that the iCalendar RFC refers to entries as
       "components".)  It is a subclass of Data::ICal::Entry and accepts all of its methods.

METHODS

   new
       Creates a new Data::ICal::Entry::Alarm::Audio object; sets its "ACTION" property to
       "AUDIO".

   ical_entry_type
       Returns "VALARM", its iCalendar entry name.

   optional_unique_properties
       According to the iCalendar standard, the following properties may be specified at most one
       time for an audio alarm:

               duration repeat attach

       Note that if one of "duration" or "repeat" is specified, the other one must be also,
       though this module does not enforce that restriction.

   mandatory_unique_properties
       According to the iCalendar standard, the "trigger" property must be specified exactly once
       for an audio alarm.  (In addition, the "action" property must be specified exactly once,
       but the module automatically sets it for you.)
