class ConsumerEndpoint
Defined at line 164 of file ../../third_party/perfetto/include/perfetto/ext/tracing/core/tracing_service.h
The API for the Consumer port of the Service.
Subclassed by:
1. The tracing_service_impl.cc business logic when returning it in response
to
the ConnectConsumer() method.
2. The transport layer (e.g., src/ipc) when the consumer and
the service don't talk locally but via some IPC mechanism.
Public Methods
void ~ConsumerEndpoint ()void EnableTracing (const TraceConfig & , base::ScopedFile )Enables tracing with the given TraceConfig. The ScopedFile argument is
used only when TraceConfig.write_into_file == true.
If TraceConfig.deferred_start == true data sources are configured via
SetupDataSource() but are not started until StartTracing() is called.
This is to support pre-initialization and fast triggering of traces.
The ScopedFile argument is used only when TraceConfig.write_into_file
== true.
void ChangeTraceConfig (const TraceConfig & )Update the trace config of an existing tracing session; only a subset
of options can be changed mid-session. Currently the only
supported functionality is expanding the list of producer_name_filters()
(or removing the filter entirely) for existing data sources.
void StartTracing ()Starts all data sources configured in the trace config. This is used only
after calling EnableTracing() with TraceConfig.deferred_start=true.
It's a no-op if called after a regular EnableTracing(), without setting
deferred_start.
void DisableTracing ()void CloneSession (CloneSessionArgs )void Flush (uint32_t timeout_ms, FlushCallback callback, FlushFlags )void Flush (uint32_t timeout_ms, FlushCallback callback)This is required for legacy out-of-repo clients like arctraceservice which
use the 2-version parameter.

void ReadBuffers ()Tracing data will be delivered invoking Consumer::OnTraceData().
void FreeBuffers ()void Detach (const std::string & key)Will call OnDetach().
void Attach (const std::string & key)Will call OnAttach().
void GetTraceStats ()Will call OnTraceStats().
void ObserveEvents (uint32_t events_mask)Start or stop observing events of selected types. |events_mask| specifies
the types of events to observe in a bitmask of ObservableEvents::Type.
To disable observing, pass 0.
Will call OnObservableEvents() repeatedly whenever an event of an enabled
ObservableEventType occurs.
TODO(eseckler): Extend this to support producers
&
data sources.
