1 | babeltrace-sink.utils.dummy(7) |
| 2 | ============================== | |
| 3 | :manpagetype: component class | |

| 7 | NAME | |
| 8 | ---- | |
| 9 | babeltrace-sink.utils.dummy - Babeltrace's dummy sink component class | |
| 10 | ||
| 11 | ||
| 12 | DESCRIPTION | |
| 13 | ----------- | |
| 14 | The Babeltrace compcls:sink.utils.dummy component class, provided by the | |
| 15 | man:babeltrace-plugin-utils(7) plugin, once instantiated, receives | |
| 16 | notifications from its input port and discards them (does absolutely | |
| 17 | nothing with them). | |
| 18 | ||
| 19 | A compcls:sink.utils.dummy sink component can be useful to run a trace | |
| 20 | processing graph with no sink side effect, for example to perform | |
| 21 | benchmarks. You should prefer this component class for such tasks | |
| 22 | instead of, for example, using a compcls:sink.text.pretty component and | |
| 23 | sending its output to `/dev/null`, as a compcls:sink.text.pretty | |
| 24 | component still performs pretty-printing operations. | |
| 25 | ||
| 26 | ||
