=head1 NAME
Travel::Status::DE::EFA::Result - Information about a single
departure received by Travel::Status::DE::EFA
=head1 SYNOPSIS
for my $departure ($status->results) {
printf(
"At %s: %s to %s from platform %d\n",
$departure->datetime->strftime('%H:%M'), $departure->line,
$departure->destination, $departure->platform
);
}
=head1 VERSION
version 2.02
=head1 DESCRIPTION
Travel::Status::DE::EFA::Result describes a single departure as obtained by
Travel::Status::DE::EFA. It contains information about the time, platform,
line number and destination.
=head1 METHODS
=head2 ACCESSORS
=over
=item $departure->countdown
Time in minutes from now until the tram/bus/train will depart, including
realtime data if available.
If delay information is available, it is already included.
=item $departure->datetime
DateTime(3pm) object for departure date and time. Realtime data if available,
schedule data otherwise.
=item $departure->delay
Expected delay from scheduled departure time in minutes. A delay of 0
indicates departure on time. undef when no realtime information is available.
=item $departure->destination
Destination name.
=item $departure->info
Additional information related to the departure (string). If departures for
an address were requested, this is the stop name, otherwise it may be recent
news related to the line's schedule. If no information is available, returns
an empty string.
=item $departure->is_cancelled
1 if the departure got cancelled, 0 otherwise.
=item $departure->key
Unknown. Unlike the name may suggest, this is not a unique key / UUID for a
departure: On the same day, different lines departing at the same station
may have the same key. It might, however, be unique when combined with the
B<line> information.
=item $departure->line
The name/number of the line.
=item $departure->lineref
Travel::Status::DE::EFA::Line(3pm) object describing the departing line in
detail.
=item $departure->mot
Returns the "mode of transport" number. This is usually an integer between 0
and 11.
=item $departure->mot_name
Returns the "mode of transport", for instance "zug", "s-bahn", "tram" or
"sonstige".
=item $departure->occupancy
Returns expected occupancy, if available, undef otherwise.
Occupancy values are passed from the backend as-is. Known values are
"MANY_SEATS" (low occupation), "FEW_SEATS" (high occupation),
"STANDING_ONLY" (very high occupation), and "FULL" (boarding not advised).
=item $departure->platform
Departure platform number (may not be a number).
=item $departure->platform_db
true if the platform number is operated by DB ("Gleis x"), false ("Bstg. x")
otherwise.
Unfortunately, there is no distinction between tram and bus platforms yet,
which may also have the same numbers.
=item $departure->route_interesting
List of up to three "interesting" stations served by this departure. Is a
subset of B<route_post>. Each station is a Travel::Status::DE::EFA::Stop(3pm)
object.
=item $departure->route_pre
List of stations the vehicle passed (or will have passed) before this stop.
Each station is a Travel::Status::DE::EFA::Stop(3pm) object.
=item $departure->route_post
List of stations the vehicle will pass after this stop.
Each station is a Travel::Status::DE::EFA::Stop(3pm) object.
=item $departure->rt_datetime
DateTime(3pm) object holding the departure date and time according to
realtime data. Undef if unknown / unavailable.
=item $departure->sched_datetime
DateTime(3pm) object holding the scheduled departure date and time.
=item $departure->train_type
Train type, e.g. "ICE". Typically only defined for long-distance trains.
=item $departure->train_name
Train name, e.g. "ICE International" or "InterCityExpresS" or "Deichgraf".
Typically only defined for long-distance trains.
=item $departure->train_no
Train number. Only defined if departure is a train.
=item $departure->type
Type of the departure. Note that efa.vrr.de sometimes puts bogus data in this
field. See L</DEPARTURE TYPES>.
=back
=head2 INTERNAL
=over
=item $departure = Travel::Status::DE::EFA::Result->new(I<%data>)
Returns a new Travel::Status::DE::EFA::Result object. You should not need to
call this.
=item $departure->TO_JSON
Allows the object data to be serialized to JSON.
=back
