=head1 NAME
Travel::Status::DE::URA::Result - Information about a single
departure received by Travel::Status::DE::URA
=head1 SYNOPSIS
for my $departure ($status->results) {
printf(
"At %s: %s to %s (in %d minutes)",
$departure->time, $departure->line, $departure->destination,
$departure->countdown
);
}
=head1 VERSION
version 2.00
=head1 DESCRIPTION
Travel::Status::DE::URA::Result describes a single departure as obtained by
Travel::Status::DE::URA. It contains information about the time,
line number and destination.
=head1 METHODS
=head2 ACCESSORS
=over
=item $departure->countdown
Time in minutes from the time Travel::Status::DE::URA was instantiated until
the bus will depart.
=item $departure->countdown_sec
Time in seconds from the time Travel::Status::DE::URA was instantiated until
the bus will depart.
=item $departure->date
Departure date (DD.MM.YYYY)
=item $departure->datetime
DateTime object holding the departure date and time.
=item $departure->destination
Destination name.
=item $departure->line
The name of the line.
=item $departure->line_id
The number of the line.
=item $departure->platform
Shortcut for $departure->stop_indicator, see there.
=item $departure->route_interesting(I<num_stops>)
If the B<results> method of Travel::Status::DE::URA(3pm) was called with
B<calculate_routes> => true: Returns a list of up to I<num_stops> (defaults to
3) stops considered interesting (usually of major importance in the transit
area). Each stop is a Travel::Status::DE::URA::Stop(3pm) object. Note that the
importance is determined heuristically based on the stop name, so it is not
always accurate.
Returns an empty list if B<calculate_routes> was false.
=item $departure->route_pre
If the B<results> method of Travel::Status::DE::URA(3pm) was called with
B<calculate_routes> => true:
Returns a list containing all stops after the requested one.
Each stop is a Travel::Status::DE::URA::Stop(3pm) object.
Returns an empty list otherwise.
=item $departure->route_post
Same as B<route_pre>, but contains the stops before the requested one.
=item $departure->stop
The stop (name, not object) belonging to this departure.
=item $departure->stop_id
The stop ID belonging to this departure.
=item $departure->stop_indicator
The indicator for this departure at the corresponding stop, usually
describes a platform or sub-stop number. undef if the stop does not
have such a distinction.
=item $departure->time
Departure time (HH:MM:SS).
=item $departure->type
Vehicle type for this departure. At the moment, this always returns "Bus".
This option exists for compatibility with other Travel::Status libraries.
=back
=head2 INTERNAL
=over
=item $departure = Travel::Status::DE::URA::Result->new(I<%data>)
Returns a new Travel::Status::DE::URA::Result object. You should not need to
call this.
=item $departure->TO_JSON
Allows the object data to be serialized to JSON.
=back
=head1 DIAGNOSTICS
None.
=head1 DEPENDENCIES
=over
=item Class::Accessor(3pm)
=back
=head1 BUGS AND LIMITATIONS
Unknown.
