9       The various nmessage types are represented as subclasses:
10
11       GStreamer::Message::EOS
12       GStreamer::Message::Error
13       GStreamer::Message::Warning
14       GStreamer::Message::Info
15       GStreamer::Message::Tag
16       GStreamer::Message::Buffering
17       GStreamer::Message::StateChanged
18       GStreamer::Message::StateDirty
19       GStreamer::Message::StepDone
20       GStreamer::Message::ClockProvide
21       GStreamer::Message::ClockLost
22       GStreamer::Message::NewClock
23       GStreamer::Message::StructureChange
24       GStreamer::Message::StreamStatus
25       GStreamer::Message::Application
26       GStreamer::Message::Element
27       GStreamer::Message::SegmentStart
28       GStreamer::Message::SegmentDone
29       GStreamer::Message::Duration

31       To create a new message, you call the constructor of the corresponding
32       class.
33
34       To check if a message is of a certain type, use the & operator on the
35       type method:
36
37         if ($message -> type & "error") {
38           # ...
39         }
40
41         elsif ($message -> type & "eos") {
42           # ...
43         }
44
45       To get to the content of a message, call the corresponding accessor:
46
47         if ($message -> type & "state-changed") {
48           my $old_state = $message -> old_state;
49           my $new_state = $message -> new_state;
50           my $pending = $message -> pending;
51
52           # ...
53         }
54
55         elsif ($message -> type & "segment-done") {
56           my $format = $message -> format;
57           my $position = $message -> position;
58
59           # ...
60         }
61

METHODS

63       structure = $message->get_structure
64
65       messagetype = $message->type
