You pass it the start/stop of your journey, maybe a time and a date and more details, and it returns the up-to-date scheduled connections between those two stops. It uses B and B for this. =head1 METHODS =over =item $efa = Travel::Routing::DE::EFA->new(I<%opts>) Returns a new Travel::Routing::DE::EFA object and sets up its POST data via %opts. Valid hash keys and their values are: =over =item B => I Mandatory. Sets the entry point to the EFA itinerary service. The following URLs (grouped by country) are known. A service marked with [!] is not completely supported yet and may not work at all. =over =item * Austria =over =item * L (Innsbrucker Verkehrsbetriebe) =item * L (Salzburger Verkehrsverbund) =item * L (Verkehrsverbund Ost-Region) =item * L (Vorarlberger Verkehrsverbund) =item * L (Verkehrsverbund Steiermark) B<[!]> =item * L (Linz AG) B<[!]> =back =item * Germany =over =item * L (Verkehrsverbund GroEraum NErnberg) =item * L (Verkehrsverbund Rhein-Ruhr) =item * L (Verkehrsverbund Rhein-Ruhr with support for B<--full-route>) =item * L (Verkehrsverbund Stuttgart) =back =back If you found a URL not listed here, please send it to Ederf@finalrewind.orgE. =item B => B<[> IB<,> I [ B<,> I ] B<]> Mandatory. Sets the start of the journey. I is optional and may be one of B (default), B
(street and house number) or B ("point of interest"). =item B => B<[> IB<,> I [ B<,> I ] B<]> Mandatory. Sets the end of the journey, see B. =item B => B<[> IB<,> I [ B<,> I ] B<]> Optional. Specifies an intermediate stop which the resulting itinerary must contain. See B for arguments. =item B => I Journey end time =item B => I Journey start time. Default: now =item B => I[I] Journey date. Default: today =item B => \@exclude Do not use certain transport types for itinerary. Accepted arguments: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus, schnellbus, seilbahn, schiff, ast, sonstige =item B => I Set maximum number of interchanges =item B => I Return up to I connections. If unset, the default of the respective EFA server is used (usually 4 or 5). =item B => B|B|B Prefer either fast connections (default), connections with low wait time or connections with little distance to walk =item B => B<0>|B<1> If true: Try using near stops instead of the specified origin/destination ones =item B => B|B|B Include only local trains into itinarery (default), all but ICEs, or all. The latter two are usually way more expensive for short routes. =item B => B|B|B Set walk speed. Default: B =item B => B<0>|B<1> If true: Prefer connections allowing passengers with bikes =item B => I<\%hashref> Options to pass to C<< LWP::UserAgent->new >>. =item B => B<0>|B<1> By default, B will create a POST request and submit it. If you do not want it to be submitted yet, set this to B<0>. =back =item $efa->submit(I<%opts>) Submit the query to I. I<%opts> is passed on to C<< LWP::UserAgent->new >>. =item $efa->routes Returns a list of Travel::Routing::DE::EFA::Route(3pm) elements. Each one contains one method of getting from start to stop. =back =head2 ACCESSORS The following methods act like the arguments to B.
