| 25 | |
| 26 | compcls:filter.utils.trimmer:: |
| 27 | Discards all the consumed messages with a time outside a given |
| 28 | time range, effectively ``cutting'' trace streams. |

| 30 | See man:babeltrace2-filter.utils.trimmer(7). |
| 31 | |
| 32 | compcls:sink.utils.counter:: |

| 34 | periodically. |

| 36 | See man:babeltrace2-sink.utils.counter(7). |
| 37 | |
| 38 | compcls:sink.utils.dummy:: |
| 39 | Consumes messages and discards them (does nothing with them). |

| 42 | application, for example. |
