DESCRIPTION

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
30       GStreamer::Message::Latency [0.10.12]
31       GStreamer::Message::AsyncStart [0.10.13]
32       GStreamer::Message::AsyncDone [0.10.13]
33
34       To create a new message, you call the constructor of the corresponding
35       class.
36
37       To check if a message is of a certain type, use the & operator on the
38       type method:
39
40         if ($message -> type & "error") {
41           # ...
42         }
43
44         elsif ($message -> type & "eos") {
45           # ...
46         }
47
48       To get to the content of a message, call the corresponding accessor:
49
50         if ($message -> type & "state-changed") {
51           my $old_state = $message -> old_state;
52           my $new_state = $message -> new_state;
53           my $pending = $message -> pending;
54
55           # ...
56         }
57
58         elsif ($message -> type & "segment-done") {
59           my $format = $message -> format;
60           my $position = $message -> position;
61
62           # ...
63         }
64

METHODS

66   object = $message->src
67   structure = $message->get_structure
68   64 bit unsigned = $message->timestamp
69   messagetype = $message->type
