babeltrace2-sink.utils.dummy - Babeltrace 2's dummy sink component class

A Babeltrace 2 sink.utils.dummy component consumes messages and discards them (does absolutely nothing with them).

A sink.utils.dummy sink component can be useful to run a trace processing graph with no sink side effect, for example to perform benchmarks. Prefer a sink.utils.dummy component class for such tasks to, for example, a sink.text.pretty component and sending its output to /dev/null, as a sink.text.pretty component still performs formatting operations.
