=head1 NAME
Travel::Routing::DE::VRR::Route::Part - Describes one connection between two
points, without interchanges
=head1 SYNOPSIS
for my $part ( $route->parts ) {
if ( $part->extra ) {
say join( "\n", $part->extra );
}
printf(
"%s at %s -> %s at %s, via %s to %s",
$part->departure_time, $part->departure_stop,
$part->arrival_time, $part->arrival_stop,
$part->train_line, $part->train_destination,
);
}
=head1 VERSION
version 0.3
=head1 DESCRIPTION
B<Travel::Routing::DE::VRR::Route::Part> holds one specific connection (without
interchanges) between two points. It specifies the start/stop point and time,
the train line and its destination, and optional additional data.
It is usually obtained by a call to Travel::Routing::DE::VRR::Route(3pm)'s
B<parts> method.
=head1 METHODS
=over
=item $part = Travel::Routing::DE::VRR::Route::Part->new(I<%data>)
Creates a new Travel::Routing::DE::VRR::Route::Part object. I<data> consists of:
=over
=item B<arrival_time> => I<HH>:I<MM>
Arrival time
=item B<arrival_stop> => I<name>
Arrival stop (city plus station / address)
=item B<departure_time> => I<HH:MM>
Departure time
=item B<departure_stop> => I<name>
Departure stop (city plus station / address)
=item B<train_destination> => I<name>
Destination of the train connecting the stops
=item B<train_line> => I<name>
The train's line name.
=item B<extra> => B<[> [ I<line1>, [ I<line2> [ I<...> ] ] ] B<]>
Additional information about this connection. Array-ref of newline-terminated
strings.
=back
=item $part->get(I<name>)
Returns the value of I<name> (B<arrival_time>, B<arrival_stop> etc., see
B<new>).
Each of these I<names> also has an accessor. So C<< $part->departure_time() >>
is the same as C<< $part->get('departure_time') >>.
=item $part->extra()
Returns a list of additional information about this route part, if provided.
Returns an empty list otherwise.
=back
=head1 DIAGNOSTICS
None.
