babeltrace2-filter.utils.muxer - Babeltrace 2: Message muxer
filter component class
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.
+-----------------+
| flt.utils.muxer |
| |
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 doesn’t 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.
+-----------------+
| flt.utils.muxer |

@ in0 out @
@ ... |
+-----------------+
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.
