=head1 NAME

Travel::Status::DE::IRIS::Result - Information about a single
arrival/departure received by Travel::Status::DE::IRIS

=head1 SYNOPSIS

	for my $result ($status->results) {
		printf(
			"At %s: %s to %s from platform %s\n",
			$result->time,
			$result->line,
			$result->destination,
			$result->platform,
		);
	}

=head1 VERSION

version 0.03

=head1 DESCRIPTION

Travel::Status::DE::IRIs::Result describes a single arrival/departure
as obtained by Travel::Status::DE::IRIS.  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->classes

List of characters indicating the class(es) of this train, may be empty. This
is slighty related to B<type>, but more generic. At this time, the following
classes are known:

    D    Non-DB train. Usually local transport
    D,F  Non-DB train, long distance transport
    F    "Fernverkehr", long-distance transport
    N    "Nahverkehr", local and regional transport
    S    S-Bahn, rather slow local/regional transport

=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->delay_messages

Get all delay messages entered for this train. Returns a list of [datetime,
string] listrefs sorted by newest first. The datetime part is a DateTime(3pm)
object corresponding to the point in time when the message was entered, the
string is the message. If a delay reason was entered more than once, only its
most recent record will be returned.

=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->is_transfer

True if the train changes its ID at the current station, false otherwise.

An ID change means: There are two results in the system (e.g. RE 10228
ME<uuml>nster -> Duisburg, RE 30028 Duisburg -> DE<uuml>sseldorf), but they are
the same train (RE line 2 from ME<uuml>nster to DE<uuml>sseldorf in this case)
and should be treated as such. In this case, Travel::Status::DE::IRIS merges
the results and indicates it by setting B<is_transfer> to a true value.

In case of a transfer, B<train_id> and B<train_no> are set to the "new"
value, the old ones are available in B<old_train_id> and B<old_train_no>.

=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->messages

Get all qos and delay messages ever entered for this train. Returns a list of
[datetime, string] listrefs sorted by newest first. The datetime part is a
DateTime(3pm) object corresponding to the point in time when the message was
entered, the string is the message. Note that neither duplicates nor superseded
messages are filtered from this list.

=item $result->old_train_id

Numeric ID of the pre-transfer train. Seems to be unique for a year and
trackable across stations. Only defined if a transfer took place,
see also B<is_transfer>.

=item $result->old_train_no

Number of the pre-tarnsfer train, unique per day. E.g. C<< 2225 >> for
C<< IC 2225 >>. See also B<is_transfer>. Only defined if a transfer took
place, see also B<is_transfer>.

=item $result->origin

Alias for route_start.

=item $result->qos_messages

Get all current qos messages for this train. Returns a list of [datetime,
string] listrefs sorted by newest first. The datetime part is a DateTime(3pm)
object corresponding to the point in time when the message was entered, the
string is the message. Contains neither superseded messages nor duplicates (in
case of a duplicate, only the most recent message is present)

=item $result->platform

Arrival/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.

=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. Does not contain realtime data.

=item $result->route_pre

List of station names the train passed (or will have passed) befoe this stop.

=item $result->route_post

List of station names the train will pass after this stop.

=item $result->route_start

Name of the first station served by this train.

=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->sched_platform

Scheduled Arrival/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->sched_route

List of all stations served by this train, according to its schedule. Does
not contain realtime data.

=item $result->sched_route_end

Name of the last station served by this train according to its schedule.

=item $result->sched_route_pre

List of station names the train is scheduled to pass before this stop.

=item $result->sched_route_post

List of station names the train is scheduled to pass after this stop.

=item $result->sched_route_start

Name of the first station served by this train according to its schedule.

=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->train_no_transfer

Number of this train after a following transfer, undefined if no such transfer
exists. See B<is_transfer> for a note about this.

Note that unlike B<old_train_no>, this information is always based on realtime
data (not included in any schedule) and only set for stations before the
transfer station, not the transfer station itself.

=item $result->type

Type of this train, e.g. C<< S >> for S-Bahn, C<< RE >> for Regional-Express,
C<< ICE >> for InterCity-Express.
