Travel::Status::DE::HAFAS::Result - Information about a single
arrival/departure received by Travel::Status::DE::HAFAS
=head1 SYNOPSIS
for my $departure ($status->results) {
printf(
"At %s: %s to %s from platform %s\n",
$departure->time,
$departure->line,
$departure->destination,
$departure->platform,

}
# or (depending on module setup)
for my $arrival ($status->results) {

"At %s: %s from %s on platform %s\n",
$arrival->time,
$arrival->line,
$arrival->origin,
$arrival->platform,
);
}
=head1 VERSION
version 1.05
=head1 DESCRIPTION
Travel::Status::DE::HAFAS::Result describes a single arrival/departure
as obtained by Travel::Status::DE::HAFAS. It contains information about
the platform, time, route and more.
=head1 METHODS
=head2 ACCESSORS
=over
=item $result->date
Arrival/Departure date in "dd.mm.yyyy" format.
=item $result->delay
Returns the train's delay in minutes, or undef if it is unknown.
Also returns undef if the train has been cancelled.
=item $result->info
Returns additional information, for instance the most recent delay reason.
Returns an empty string if no (useful) information is available.
=item $result->is_cancelled
True if the train was cancelled, false otherwise.
=item $result->is_changed_platform
True if the platform (as returned by the B<platform> accessor) is not the
scheduled one. Note that the scheduled platform is unknown in this case.
=item $result->messages
Returns a list of message strings related to this train. Messages usually are
service notices (e.g. "missing carriage") or detailed delay reasons
(e.g. "switch damage between X and Y, expect delays").
=item $result->line
=item $result->train
Returns the line name, either in a format like "S 1" (S-Bahn line 1)
or "RE 10111" (RegionalExpress train 10111, no line information).
=item $result->platform
Returns the platform from which the train will depart / at which it will
arrive. Realtime data if available, schedule data otherwise.
=item $result->route_end
Returns the last element of the route. Depending on how you set up
Travel::Status::DE::HAFAS (arrival or departure listing), this is
either the train's destination or its origin station.
=item $result->destination
=item $result->origin
Convenience aliases for C<< $result->route_end >>.
=item $result->time
Returns the arrival/departure time as string in "hh:mm" format.
=item $result->type
Returns the type of this train, e.g. "S" for S-Bahn, "RE" for Regional Express
or "ICE" for InterCity-Express.
=back
=head2 INTERNAL
=over
=item $result = Travel::Status::DE::HAFAS::Result->new(I<%data>)

=item B<train> => I<string>
=item B<route_end> => I<string>
=item B<platform> => I<string>
=item B<info_raw> => I<string>
