NAME         top

       babeltrace-filter.utils.muxer - Babeltrace's notification multiplexer
       filter component class

DESCRIPTION         top

       The Babeltrace filter.utils.muxer component class, provided by the
       babeltrace-plugin-utils(7) plugin, once instantiated, multiplexes the
       notifications that it receives from one or more input ports into a
       linear sequence of events ordered by time on its output port.

       A filter.utils.muxer component does not alter the notifications it
       receives: it only sorts them.

       A filter.utils.muxer component can only work on notifications in
       which the clock value with the highest priority has an absolute clock
       class. You can use the assume-absolute-clock-classes parameter to
       make the component assume that all clock classes are absolute. In
       this case, you must ensure that, when more than one clock class
       exists, they are correlatable.

INITIALIZATION PARAMETERS         top

       The following parameters are optional.

       assume-absolute-clock-classes=yes (boolean)
           Assume that all clock classes are absolute.

PORTS         top

   Input
       inN, where N is a decimal integer starting at 0
           Input port from which the component receives notifications to
           multiplex.

           When you create the component, its only input port is in0. When
           you connect the in0 port, the component creates the in1 input
           port, and so on. If you disconnect an input port, the component
           does not create a new input port: the disconnected input port is
           now available for a new connection.

           In other words, a filter.utils.muxer component always makes sure
           that it has at least one available input port.

   Output
       out
           Single output port to which the component sends the sorted
           notifications.

QUERY OBJECTS         top

       This component class has no objects to query.

ENVIRONMENT VARIABLES         top

       BABELTRACE_COMMON_LOG_LEVEL
           Common functions’s log level. The available values are the same
           as for the --log-level option of babeltrace(1).

       BABELTRACE_COMPAT_LOG_LEVEL
           Compatibility functions’s log level. The available values are the
           same as for the --log-level option of babeltrace(1).

       BABELTRACE_TERM_COLOR
           Force the terminal color support. The available values are:

           AUTO
               Only emit terminal color codes when the standard output and
               error streams are connected to a color-capable terminal.

           NEVER
               Never emit terminal color codes.

           ALWAYS
               Always emit terminal color codes.

       BABELTRACE_FLT_UTILS_MUXER_LOG_LEVEL
           Component class’s log level. The available values are the same as
           for the --log-level option of babeltrace(1).
