It contains information about the platform, time, route and more. =head1 METHODS =head2 ACCESSORS =over =item $result->arrival DateTime(3pm) object for the arrival date and time. undef if the train starts here. Contains realtime data if available. =item $result->date Scheduled departure date if available, arrival date otherwise (e.g. if the train ends here). String in dd.mm.YYYY format. Does not contain realtime data. =item $result->datetime DateTime(3pm) object for departure if available, arrival otherwise. Does not contain realtime data. =item $result->delay Estimated delay in minutes (integer number). undef when no realtime data is available, negative if a train ends at the specified station and arrives / arrived early. =item $result->departure DateTime(3pm) object for the departure date and time. undef if the train ends here. Contains realtime data if available. =item $result->destination Aleas for route_end. =item $result->info List of information strings. Contains both reasons for delays (which may or may not be up-to-date) and generic information such as missing carriages or broken toilets. =item $result->is_cancelled True if the train was cancelled, false otherwise. Note that this does not contain information about replacement trains or route diversions. =item $result->line Train type with line (such as C<< S 1 >>) if available, type with number (suc as C<< RE 10126 >>) otherwise. =item $result->line_no Number of the line, undef if unknown. Seems to be set only for S-Bahn and similar trains. Regional and long-distance trains such as C<< RE 10126 >> usually do not have this field set, even if they have a common line number (C<< RE 1 >> in this case). Example: For the line C<< S 1 >>, line_no will return C<< 1 >>. =item $result->origin Alias for route_start. =item $result->platform Arrivel/departure platform as string, undef if unknown. Note that this is not neccessarily a number, platform sections may be included (e.g. C<< 3a/b >>). =item $result->raw_id Raw ID of the departure, e.g. C<< -4642102742373784975-1401031322-6 >>. The first part appears to be this train's UUID (can be tracked across multiple stations), the second the YYmmddHHMM departure timestamp at its start station, and the third the count of this station in the train's schedule (in this case, it's the sixth from thestart station). About half of all departure IDs do not contain the leading minus (C<< - >>) seen in this example. The reason for this is unknown. This is a developer option. It may be removed without prior warning. =item $result->realtime_xml XML::LibXML::Node(3pm) object containing all realtime data. undef if none is available. This is a developer option. It may be removed without prior warning. =item $result->route List of all stations served by this train, according to its schedule. Does not contain realtime data. =item $result->route_end Name of the last station served by this train according to its schedule. =item $result->route_interesting List of up to three "interesting" stations served by this train, subset of route_post. Usually contains the next stop and one or two major stations after that. =item $result->route_pre List of station names the train is scheduled to pass before this stop. =item $result->route_post List of station names the train is scheduled to pass after this stop. =item $result->route_start Name of the first station served by this train according to its schedule. =item $result->sched_arrival DateTime(3pm) object for the scheduled arrival date and time. undef if the train starts here. =item $result->sched_departure DateTime(3pm) object for the scehduled departure date and time. undef if the train ends here. =item $result->start DateTime(3pm) object for the scheduled start of the train on its route (i.e. the departure time at its first station). =item $result->stop_no Number of this stop on the train's route. 1 if it's the start station, 2 for the stop after that, and so on. =item $result->time Scheduled departure time if available, arrival time otherwise (e.g. if the train ends here). String in HH:MM format. Does not contain realtime data. =item $result->train Alias for line. =item $result->train_id Numeric ID of this train. Seems to be unique for a year and trackable across stations. =item $result->train_no Number of this train, unique per day. E.g. C<< 2225 >> for C<< IC 2225 >>. =item $result->type Type of this train, e.g. C<< S >> for S-Bahn, C<< RE >> for Regional-Express, C<< ICE >> for InterCity-Express. =back =head2 INTERNAL =over =item $result = Travel::Status::DE::IRIS::Result->new(I<%data>) Returns a new Travel::Status::DE::IRIS::Result object. You usually do not need to call this. =back =head1 MESSAGES A dump of all messages entered for the result is available.
