timestamp()

ITraceCounter* timestamp(u64 timestamp, ClockType clock)

Sets the timestamp of the value for counter track defined by ITraceCounter.

​

Parameters

timestamp

u64 — Required Timestamp of tracepoint.

clock

ClockType — Required ClockType enum used to set Perfetto clock type.

​

Returns

ITraceCounter* ITraceCounter with set timestamp.

valueInt32()

ITraceCounter* valueInt32(i32 value)

Emit a counter value of type int32_t for counter track defined by ITraceCounter. set by ITraceCounterBuilder.

​

Parameters

value

i32 — Required Value of counter.

​

Returns

ITraceCounter* original ITraceCounter object

---

​

valueInt64()

ITraceCounter* valueInt64(i64 value)

Emit a counter value of type int64_t for counter track defined by ITraceCounter. set by ITraceCounterBuilder.

​

Parameters

value

i64 — Required Value of counter.

---

​

valueDouble()

ITraceCounter* valueDouble(double value)

Emit a counter value of type double for counter track defined by ITraceCounter. set by ITraceCounterBuilder.

​

Parameters

value

double — Required Value of counter.

​

Returns

ITraceCounter* original ITraceCounter object

​

emit()

void emit()

Emit a counter with the passed value and timestamp defined by ITraceCounter If a timestamp is not defined, the timestamp will default to now Note, when a counter is emitted the timestamp will be reset
