26 | @brief | |
27 | Trace stream. | |
28 | ||
29 | A <strong><em>stream</em></strong> is a conceptual | |
30 | \ref api-msg-seq "sequence of messages" within a \bt_trace: | |
31 | ||
32 | @image html trace-structure.png | |
33 | ||
34 | In the illustration above, notice that: | |
35 | ||
36 | - A \bt_stream is a conceptual sequence of \bt_p_msg. | |
37 | ||
38 | The sequence always starts with a \bt_sb_msg and ends with a | |
39 | \bt_se_msg. | |
40 | ||
41 | - A stream is an instance of a \bt_stream_cls. | |
42 | ||
43 | - A \bt_trace contains one or more streams. | |
44 | ||
45 | A stream is a \ref api-tir "trace IR" data object. | |
46 | ||
47 | A stream is said to be a \em conceptual sequence of messages because the | |
48 | stream object itself does not contain messages: it only represents a | |
49 | common timeline to which messages are associated. | |
50 | ||
51 | \bt_cp_comp exchange messages, within a trace processing \bt_graph, | |
52 | which can belong to different streams, as long as the stream clocks are | |
53 | \ref api-tir-clock-cls-origin "correlatable". | |
54 | ||
55 | A typical use case for streams is to use one for each traced CPU. Then | |
118ae153 | 56 | the messages related to a given stream are the ones which occurred on a |
43c59509 PP |
57 | given CPU. Other schemes are possible: they are completely |
58 | application-specific, and \bt_name does not enforce any specific | |
59 | stream arrangement pattern. | |
60 | ||
61 | A \bt_trace contains streams. All the streams of a | |
62 | given trace, for a given stream class, have unique numeric IDs. Borrow | |
63 | the trace which contains a stream with bt_stream_borrow_trace() or | |
64 | bt_stream_borrow_trace_const(). | |
65 | ||
66 | A \bt_stream can conceptually contain a default clock if its class | |
67 | has a \ref api-tir-stream-cls-prop-def-clock-cls "default clock class". | |
68 | There's no function to access a stream's default clock because it's | |
69 | a stateful object: \bt_p_msg cannot refer to stateful objects | |
70 | because they must not change while being transported from one | |
71 | \bt_comp to the other. Instead of having a stream default clock object, | |
72 | \bt_p_msg have a default \bt_cs: this is a snapshot of the value of a | |
73 | stream's default clock (a \bt_clock_cls instance): | |
74 | ||
75 | @image html clocks.png | |
76 | ||
77 | In the illustration above, notice that: | |
78 | ||
79 | - Streams (horizontal blue rectangles) are instances of a | |
80 | \bt_stream_cls (orange). | |
81 | ||
82 | - A stream class has a default \bt_clock_cls (orange bell alarm clock). | |
83 | ||
84 | - Each stream has a default clock (yellow bell alarm clock): this is an | |
85 | instance of the stream's class's default clock class. | |
86 | ||
87 | - Each \bt_msg (objects in blue stream rectangles) created for a given | |
88 | stream has a default \bt_cs (yellow star): this is a snapshot of the | |
89 | stream's default clock. | |
90 | ||
91 | In other words, a default clock snapshot contains the value of the | |
118ae153 | 92 | stream's default clock when this message occurred. |
43c59509 PP |
93 | |
94 | To create a stream: | |
95 | ||
96 | <dl> | |
97 | <dt> | |
98 | If bt_stream_class_assigns_automatic_stream_id() returns | |
99 | #BT_TRUE (the default) for the stream class to use | |
100 | </dt> | |
101 | <dd>Use bt_stream_create().</dd> | |
102 | ||
103 | <dt> | |
104 | If bt_stream_class_assigns_automatic_stream_id() returns | |
105 | #BT_FALSE for the stream class to use | |
106 | </dt> | |
107 | <dd>Use bt_stream_create_with_id().</dd> | |
108 | </dl> | |
109 | ||
110 | A stream is a \ref api-fund-shared-object "shared object": get a | |
111 | new reference with bt_stream_get_ref() and put an existing | |
112 | reference with bt_stream_put_ref(). | |
113 | ||
114 | Some library functions \ref api-fund-freezing "freeze" streams on | |
115 | success. The documentation of those functions indicate this | |
116 | postcondition. | |
117 | ||
118 | The type of a stream is #bt_stream. | |
119 | ||
120 | <h1>Properties</h1> | |
121 | ||
122 | A stream has the following property: | |
123 | ||
124 | <dl> | |
125 | <dt>\anchor api-tir-stream-prop-id Numeric ID</dt> | |
126 | <dd> | |
127 | Numeric ID, unique amongst the numeric IDs of the stream's | |
128 | \bt_trace's streams for a given \bt_stream_cls. In other words, | |
129 | two streams which belong to the same trace can have the same numeric | |
130 | ID if they aren't instances of the same class. | |
131 | ||
132 | Depending on whether or not the stream's class | |
133 | automatically assigns stream IDs | |
134 | (see bt_stream_class_assigns_automatic_stream_id()), | |
135 | set the stream's numeric ID on creation with | |
136 | bt_stream_create() or bt_stream_create_with_id(). | |
137 | ||
138 | You cannot change the numeric ID once the stream is created. | |
139 | ||
140 | Get a stream's numeric ID with bt_stream_get_id(). | |
141 | </dd> | |
142 | ||
143 | <dt>\anchor api-tir-stream-prop-name \bt_dt_opt Name</dt> | |
144 | <dd> | |
145 | Name of the stream. | |
146 | ||
147 | Use bt_stream_set_name() and bt_stream_get_name(). | |
148 | </dd> | |
149 | ||
150 | <dt> | |
151 | \anchor api-tir-stream-prop-user-attrs | |
152 | \bt_dt_opt User attributes | |
153 | </dt> | |
154 | <dd> | |
155 | User attributes of the stream. | |
156 | ||
157 | User attributes are custom attributes attached to a stream. | |
158 | ||

160 | bt_stream_borrow_user_attributes(), and | |
161 | bt_stream_borrow_user_attributes_const(). | |
