It contains information about the time, platform, line number and destination. =head1 METHODS =head2 ACCESSORS "Actual" in the description means that the delay (if available) is already included in the calculation, "Scheduled" means it isn't. =over =item $departure->countdown Actual time in minutes from now until the tram/bus/train will depart. If delay information is available, it is already included. =item $departure->date Actual departure date (DD.MM.YYYY). =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 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->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. Each station is a Travel::Status::DE::EFA::Stop(3pm) object. =item $departure->route_pre List of stations the train passed (or will have passed) befoe this stop. Each station is a Travel::Status::DE::EFA::Stop(3pm) object. =item $departure->route_post List of stations the train will pass after this stop. Each station is a Travel::Status::DE::EFA::Stop(3pm) object. =item $departure->sched_date Scheduled departure date (DD.MM.YYYY). =item $departure->sched_time Scheduled departure time (HH:MM). =item $departure->time Actual departure time (HH:MM). =item $departure->type Type of the departure. Note that efa.vrr.de sometimes puts bogus data in this field. See L. =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 =head1 DEPARTURE TYPES The following are known so far: =over =item * Abellio-Zug =item * Bus =item * Eurocity =item * Intercity-Express =item * NE (NachtExpress / night bus) =item * Niederflurbus =item * R-Bahn (RE / RegionalExpress) =item * S-Bahn =item * SB (Schnellbus) =item * StraEenbahn =item * U-Bahn =back =head1 DIAGNOSTICS None. =head1 DEPENDENCIES =over =item Class::Accessor(3pm) =back =head1 BUGS AND LIMITATIONS C<< $result->type >> may contain bogus data. This comes from the efa.vrr.de interface. =head1 SEE ALSO Travel::Status::DE::EFA(3pm). =head1 AUTHOR Copyright (C) 2011-2015 by Daniel Friesel Ederf@finalrewind.orgE =head1 LICENSE This module is licensed under the same terms as Perl itself.
