=head1 SYNOPSIS
if ($message->text) {
printf("%s: %s\n", $message->short, $message->text);
}
else {
say $message->short;
}
=head1 VERSION
version 6.09
=head1 DESCRIPTION
Travel::Status::DE::HAFAS::Message describes a message belonging to an
arrival or departure. Messages may refer to planned schedule changes due to
construction work, the expected passenger volume, or similar.
=head1 METHODS
=head2 ACCESSORS
=over
=item $message->short
Message header. May be a concise single-sentence summary or a mostly useless
string such as "Information". Does not contain newlines.
=item $message->text
Detailed message content. Does not contain newlines.
=item $message->code
Two-digit message code, seems to be only used with messages of type "A".
Details unknown.
=item $message->type
A single character indicating the message type.
The following types are known:
=over
=item A
Generic information about a specific trip such as "WiFi available", "air
conditioning", "DB tickets are not valid here", or "from here on as [line]
towards [destination]".
=item C
"Current information available", "Journey cancelled", "connection may not be caught", possibly more.
=item D
Large-scale disruption, e.g. medical emergency on line.
=item G
Platform change, possibly more.
=item H
Misc stuff such as "Journey contains trains with mandatory reservation" or
"ICE Sprinter".
=item L
Replacement journey
=item M
Free-text infos about construction sites, broken elevators, large events and
similar occasions.
=item P
Journey has been cancelled, possibly more.
=back
=item $message->ref_count
Counter indicating how often this message is used by the requested
arrivals/departures. ref_count is an integer between 1 and the number of
results. If ref_count is 1, it is referenced by a single result only.
=item $message->is_him
True if it is a HIM message (typically used for service information), false
if not (message may be a REM instead, indicating e.g. presence of a bicycle
carriage or WiFi).
