To create a new message, you call the constructor of the corresponding class.

To check if a message is of a certain type, use the & operator on the type method:

if ($message -> type & "error") {
  # ...
}

elsif ($message -> type & "eos") {
  # ...
}

To get to the content of a message, call the corresponding accessor:

if ($message -> type & "state-changed") {
  my $old_state = $message -> old_state;
  my $new_state = $message -> new_state;
  my $pending = $message -> pending;

  # ...
}

elsif ($message -> type & "segment-done") {
  my $format = $message -> format;
  my $position = $message -> position;

  # ...
}
