Public Methods

Platform * GetDefaultPlatform ()

Embedders can use this unless they have custom needs (e.g. Chrome wanting

to use its own base class for TLS).

void SetCurrentProcessId (base::PlatformProcessId process_id)

Embedders can call this to set process ID in those cases where getpid()

returns incorrect values (e.g. for sandboxed processes in Chromium).

Should only be called once, before tracing has been initialized.

base::PlatformProcessId GetCurrentProcessId ()

Returns process ID previously set by SetCurrentProcessId, or the process

ID provided by the OS if no custom ID was provided.

void ~Platform ()
ThreadLocalObject * GetOrCreateThreadLocalObject ()
std::unique_ptr<base::TaskRunner> CreateTaskRunner (const CreateTaskRunnerArgs & )
std::string GetCurrentProcessName ()

Used to derive the producer name. Mostly relevant when using the

kSystemBackend mode. It can be an arbitrary string when using the

in-process mode.

void Shutdown ()

Tear down any persistent platform state (e.g., TLS variables). The platform

interface must not be used after calling this function.

base::PlatformThreadId GetCurrentThreadId ()

Returns the thread ID provided by the OS by default. Chromium uses

different thread IDs on some platforms, so it needs the ability to

override this method.
