BABELTRACE2-FILTER()                                BABELTRACE2-FILTER()

NAME         top

       babeltrace2-filter.utils.muxer - Babeltrace 2's message muxer
       filter component class

DESCRIPTION         top

       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.

       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.

           Note
           To 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.

   Input
       inN, where N is 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 the in0 port, the component creates the
           in1 input port, and so on.

           In other words, a filter.utils.muxer component always has an
           available input port.

   Output
       out
           Single output port.
