ark::perf::SchedSwitchDecoder

Defined in header “ark/perf/perf_event_decoder.hh”.

---

This class is capable of decoding arbitrary ‘sched_switch’ counters. It must be initialized with a schema, and then you can pass in the raw_data field from the perf event samples.

Methods

• SchedSwitchDecoder(const PerfEventSchema & schema)
  Constructor. Decodes the format into a set of offsets to further decode the remaining data.

• SchedSwitchCounter decode(const core::ByteBuffer & buffer)
  Decodes the raw sample into a counter.
