babeltrace2-filter.utils.muxer(7)
NAME
babeltrace2-filter.utils.muxer — Babeltrace 2's message muxer filter component class
DESCRIPTION
A Babeltrace 2 filter.utils.muxer message iterator muxes the messages that it consumes from one or more upstream message iterators into a linear sequence of messages ordered by time.
+-----------------+

Messages -->@ in0 out @--> Sorted messages
Messages -->@ in1 |
Messages -->@ in2 |
@ in3 |
+-----------------+See babeltrace2-intro(7) to learn more about the Babeltrace 2 project and its core concepts.
A filter.utils.muxer message iterator does not alter the messages it consumes: it only sorts them.
The message iterator creates one upstream message iterator per connected input port.
NoteTo support muxing messages with different default clock classes, the message iterator converts the message times to nanoseconds from the common origin (Unix epoch, for example). This means that the resulting message sequence could be incorrect if one or more clock classes have a frequency which is greater than 1 GHz.
PORTS

+-----------------+Input
-
inN, whereNis a decimal integer starting at 0 -
Input port on which a filter.utils.muxer message iterator creates an upstream message iterator to consumes messages from.
When the component is initialized, its only input port is
in0. When you connect thein0port, the component creates thein1input port, and so on.In other words, a filter.utils.muxer component always has an available input port.
Output
-
out -
Single output port.
