объект запроса информации о трассировке Babeltrace 2 (Babeltrace 2's trace infos query object)

Имя (Name)

babeltrace2-query-babeltrace.trace-infos - Babeltrace 2's trace
       infos query object

Описание (Description)

The babeltrace.trace-infos Babeltrace 2 query object indicates
       time range information about specific traces and their streams,
       and which output ports of an eventual source component will serve
       the messages for a given stream.

The babeltrace2-convert(1) command queries this object from all the source component classes to support the --stream-intersection feature.


Параметры (Parameters)

The parameters for this query operation are exactly the same as
       you would pass as the initialization parameters of a component
       created from the queried component class.

RESULT OBJECT

The result object is an array of trace info maps (see 'Trace info
       map').

Trace info map A trace info map contains:

stream-infos=STREAM-INFOS [array of stream info maps] Stream info maps (see 'Stream info map') for this trace.

Stream info map A stream info map contains:

range-ns=RANGE [range map] The time range of this stream, a map containing:

begin=NS [signed integer] Beginning time of this stream (nanoseconds since the stream class's default clock class's origin).

end=NS [signed integer] End time of this stream (nanoseconds since the stream class's default clock class's origin).

port-name=PORT-NAME [string] For an eventual source component initialized with the same parameters: name of the output port which serves the messages of this stream.


Примеры (Examples)

Result object
       Example 1. Two trace infos: one with three stream infos, one with
       two stream infos.
