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)
