.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A Data::ICal::Entry::Alarm::Display object represents a alarm that
displays a message which is attached to a todo item or event in an
iCalendar file.  (Note that the iCalendar \s-1RFC\s0 refers to entries as
\&\*(L"components\*(R".)  It is a subclass of Data::ICal::Entry and accepts
all of its methods.
.SH "METHODS"
.IX Header "METHODS"
.SS "new"
.IX Subsection "new"
Creates a new Data::ICal::Entry::Alarm::Display object; sets its
\&\f(CW\*(C`ACTION\*(C'\fR property to \f(CW\*(C`DISPLAY\*(C'\fR.
.SS "ical_entry_type"
.IX Subsection "ical_entry_type"
Returns \f(CW\*(C`VALARM\*(C'\fR, its iCalendar entry name.
.SS "optional_unique_properties"
.IX Subsection "optional_unique_properties"
According to the iCalendar standard, the \f(CW\*(C`duration\*(C'\fR and \f(CW\*(C`retreat\*(C'\fR
properties may be specified at most one time for an displayed alarm,
and if one is specified, the other one must be also, though this
module does not enforce that restriction.
.SS "mandatory_unique_properties"
.IX Subsection "mandatory_unique_properties"
According to the iCalendar standard, the \f(CW\*(C`trigger\*(C'\fR and \f(CW\*(C`description\*(C'\fR
properties must be specified exactly once for an displayed alarm.  (In
addition, the \f(CW\*(C`action\*(C'\fR property must be specified exactly once, but
the module automatically sets it for you.)
