◆ AddTraceEvent()

uint64_t v8::platform::tracing::TracingController::AddTraceEvent ( char  phase,
const uint8_t *  category_enabled_flag,
const char *  name,
const char *  scope,
uint64_t  id,
uint64_t  bind_id,
int32_t  num_args,
const char **  arg_names,
const uint8_t *  arg_types,
const uint64_t *  arg_values,
std::unique_ptr< v8::ConvertableToTraceFormat > *  arg_convertables,
unsigned int  flags 
)
overridevirtual

Adds a trace event to the platform tracing system. These function calls are usually the result of a TRACE_* macro from trace-event-no-perfetto.h when tracing and the category of the particular trace are enabled. It is not advisable to call these functions on their own; they are really only meant to be used by the trace macros. The returned handle can be used by UpdateTraceEventDuration to update the duration of COMPLETE events.

Reimplemented from v8::TracingController.

◆ AddTraceEventWithTimestamp()

uint64_t v8::platform::tracing::TracingController::AddTraceEventWithTimestamp ( char  phase,
const uint8_t *  category_enabled_flag,
const char *  name,
const char *  scope,

std::unique_ptr< v8::ConvertableToTraceFormat > *  arg_convertables,
unsigned int  flags,
int64_t  timestamp 
)
overridevirtual

Reimplemented from v8::TracingController.

◆ AddTraceStateObserver()

void v8::platform::tracing::TracingController::AddTraceStateObserver ( v8::TracingController::TraceStateObserver *  )
overridevirtual

Adds tracing state change observer. Does nothing in Perfetto SDK build (v8_use_perfetto = true).

Reimplemented from v8::TracingController.

◆ CurrentCpuTimestampMicroseconds()

virtual int64_t v8::platform::tracing::TracingController::CurrentCpuTimestampMicroseconds ( )
protectedvirtual

◆ CurrentTimestampMicroseconds()

virtual int64_t v8::platform::tracing::TracingController::CurrentTimestampMicroseconds ( )
protectedvirtual

◆ GetCategoryGroupEnabled()

const uint8_t * v8::platform::tracing::TracingController::GetCategoryGroupEnabled ( const char *  name)
overridevirtual

Called by TRACE_EVENT* macros, don't call this directly. The name parameter is a category group for example: TRACE_EVENT0("v8,parse", "V8.Parse") The pointer returned points to a value with zero or more of the bits defined in CategoryGroupEnabledFlags.

Reimplemented from v8::TracingController.

◆ GetCategoryGroupName()

static const char * v8::platform::tracing::TracingController::GetCategoryGroupName ( const uint8_t *  category_enabled_flag)

◆ Initialize()

void v8::platform::tracing::TracingController::Initialize ( TraceBuffer *  trace_buffer)

◆ RemoveTraceStateObserver()

void v8::platform::tracing::TracingController::RemoveTraceStateObserver ( v8::TracingController::TraceStateObserver *  )
overridevirtual

Removes tracing state change observer. Does nothing in Perfetto SDK build (v8_use_perfetto = true).

Reimplemented from v8::TracingController.

◆ StartTracing()

void v8::platform::tracing::TracingController::StartTracing ( TraceConfig *  trace_config)

◆ StopTracing()

void v8::platform::tracing::TracingController::StopTracing ( )

◆ UpdateTraceEventDuration()

void v8::platform::tracing::TracingController::UpdateTraceEventDuration ( const uint8_t *  category_enabled_flag,
const char *  name,
uint64_t  handle 
)
overridevirtual

Sets the duration field of a COMPLETE trace event. It must be called with the handle returned from AddTraceEvent().

Reimplemented from v8::TracingController.
