=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 delay in minutes, or undef if it is unknown.
Also returns undef if the arrival/departure has been cancelled.
=item $result->info
Returns additional information, for instance the most recent delay reason.
undef if no (useful) information is available.
=item $result->is_cancelled
True if the arrival/departure 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 result. 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 "Bus SB16" (Bus line SB16)
or "RE 10111" (RegionalExpress train 10111, no line information).
May contain extraneous whitespace characters.
=item $result->line_no
=item $result->train_no
Returns the line/train number, for instance "SB16" (bus line SB16),
"11" (Underground train line U 11) or 1011 ("RegionalExpress train 1011").
=item $result->platform
Returns the arrival/departure platform.
Realtime data if available, schedule data otherwise.
=item $result->route_end
=item $result->destination
=item $result->origin
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 result's destination or its origin station.
=item $result->time
Returns the arrival/departure time as string in "hh:mm" format.
=item $result->type
Returns the type of this result, e.g. "S" for S-Bahn, "RE" for Regional Express
or "STR" for tram / StraE<szlig>enbahn.
