=head1 NAME

Travel::Routing::DE::HAFAS::Connection - A single connection between two stops

=head1 SYNOPSIS

	for my $connection ( $hafas->connections ) {
		# $connection is a Travel::Routing::DE::HAFAS::Connection object
		for my $section ( $connection->sections ) {
			# $section is a Travel::Routing::DE::HAFAS::Connection::Section object
		}
	}

=head1 VERSION

version 0.07

=head1 DESCRIPTION

Travel::Routing::DE::HAFAS::Connection describes a single connection (or
itinerary) for getting from one stop to another. In addition to overall
connection information, it holds a list of
Travel::Routing::DE::HAFAS::Connection::Section(3pm) objects that describe the
individual parts of the connection.

=head1 METHODS

=head2 ACCESSORS

=over

=item $connection->arr_cancelled

True if the arrival of the last section in this connection has been cancelled,
false otherwise.

=item $connection->arr

DateTime(3pm) object holding the arrival time and date. Based on real-time data
if available, falls back to schedule data otherwise.

=item $connection->arr_loc

Travel::Status::DE::HAFAS::Location(3pm) object describing the arrival stop.

=item $connection->arr_platform

Arrival platform. Undef if unknown.

=item $connection->changes

Number of changes between different modes of transport.

=item $connection->dep_cancelled

True if the departure of the first section in this connection has been
cancelled, false otherwise.

=item $connection->dep

DateTime(3pm) object holding the departure time and date. Based on real-time
data if available, falls back to schedule data otherwise.

=item $connection->dep_loc

Travel::Status::DE::HAFAS::Location(3pm) object describing the departure stop.

=item $connection->dep_platform

Departure platform. Undef if unknown.

=item $connection->duration

DateTime::Duration(3pm) object describing the duration of this connection,
i.e., the time between departure and arrival.

=item $connection->is_cancelled

True if part of this connection has been cancelled.  Depending on the
availability of replacement service, this may or may not indicate that the
connection is no longer possible.

=item $connection->load

Maximum expected occupancy along the connection.
Returns a hashref with keys FIRST and SECOND; each value ranges from 1
(low occupancy) to 4 (fully booked).
Returns undef if occupancy data is not available.

=item $connection->messages

List of Travel::Status::DE::HAFAS::Message(3pm) objects associated with this
connection. Typically contains messages along the lines of "current information
available", "journey cancelled", or "a change between two connection sections
may not be feasible".

=item $connection->rt_arr

DateTime(3pm) object holding real-time arrival if available.
Undef otherwise.

=item $connection->rt_dep

DateTime(3pm) object holding real-time departure if available.
Undef otherwise.

=item $connection->sched_arr

DateTime(3pm) object holding scheduled arrival if available.
Undef otherwise.

=item $connection->sched_dep

DateTime(3pm) object holding scheduled departure if available.
Undef otherwise.

=item $connection->sections

List of Travel::Routing::DE::HAFAS::Connection::Section(3pm) objects that
describe the individual sections of this connection.
