=head1 NAME
Travel::Status::DE::DeutscheBahn::Result - Information about a single
arrival/departure received by Travel::Status::DE::DeutscheBahn
=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) {
printf(
"At %s: %s from %s on platform %s\n",
$arrival->time,
$arrival->line,
$arrival->origin,
$arrival->platform,
);
}
=head1 VERSION
version 1.02
=head1 DESCRIPTION
Travel::Status::DE::DeutscheBahn::Result describes a single arrival/departure
as obtained by Travel::Status::DE::DeutscheBahn. 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.
=item $result->info
Returns additional information, for instance the reason why the train is
delayed. May be an empty string if no (useful) information is available.
=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.
=item $result->route
Returns a list of station names the train will pass between the selected
station and its origin/destination.
=item $result->route_end
Returns the last element of the route. Depending on how you set up
Travel::Status::DE::DeutscheBahn (arrival or departure listing), this is
either the train's destination or its origin station.
=item $result->destination
=item $result->origin
Convenience aliases for $result->route_end.
=item $result->route_interesting([I<max>])
Returns a list of up to I<max> (default: 3) interesting stations the train
will pass on its journey. Since deciding whether a station is interesting or
not is somewhat tricky, this feature should be considered experimental.
The first element of the list is always the train's next stop. The following
elements contain as many main stations as possible, but there may also be
smaller stations if not enough main stations are available.
In future versions, other factors may be taken into account as well. For
example, right now airport stations are usually not included in this list,
although they should be.
Note that all main stations will be stripped of their "Hbf" suffix.
=item $result->route_raw
Returns the raw string used to create the route array.
Note that canceled stops are filtered from B<route>, but still present in
B<route_raw>.
=item $result->route_timetable
Similar to B<route>. however, this function returns a list of array
references of the form C<< [ arrival time, station name ] >>.
=item $result->time
Returns the arrival/departure time as string in "hh:mm" format.
=back
=head2 INTERNAL
=over
=item $result = Travel::Status::DE::DeutscheBahn::Result->new(I<%data>)
Returns a new Travel::Status::DE::DeutscheBahn::Result object.
You usually do not need to call this.
Required I<data>:

=item B<train> => I<string>
=item B<route_raw> => I<string>
=item B<route> => I<arrayref>
=item B<route_end> => I<string>
=item B<platform> => I<string>
