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>) + +Returns a new Travel::Status::DE::HAFAS::Result object. +You usually do not need to call this. + +Required I<data>: + +=over + +=item B<time> => I<hh:mm> + +=item B<train> => I<string> + +=item B<route_end> => I<string> + +=item B<platform> => I<string> + +=item B<info_raw> => I<string> + +=back + +=back + +=head1 DIAGNOSTICS + +None. + +=head1 DEPENDENCIES + +=over + +=item Class::Accessor(3pm) + +=back + +=head1 BUGS AND LIMITATIONS + +None known. + +=head1 SEE ALSO + +Travel::Status::DE::HAFAS(3pm). + +=head1 AUTHOR + +Copyright (C) 2011 by Daniel Friesel E<lt>derf@finalrewind.orgE<gt> + +=head1 LICENSE + +This module is licensed under the same terms as Perl itself. |
