class SystemData
Defined at line 56 of file ../../third_party/cobalt/src/system_data/system_data.h
The embedding client creates a singleton instance of SystemData at start-up
time and uses it to query data about the client's running system. There
are two categories of data: static data about the system encapsulated in
the SystemProfile, and dynamic stateful data about the running system.
Public Methods
void SystemData (const std::string & product_name, const std::string & board_name_suggestion, ReleaseStage release_stage, const std::string & version, SystemProfile::BuildType build_type, const std::vector<int64_t> & experiment_ids)Constructor: Uses the real SystemProfile of the actual running system.
|product_name|: The value to use for the |product_name| field of the
embedded SystemProfile.
|board_name_suggestion|: A suggestion for the value to use for the
|board_name| field of the embedded SystemProfile. This may be ignored if
SystemData is able to determine the board name directly. A value of ""
indicates that the caller has no information about board name, so one
should be guessed.
|release_stage|: The ReleaseStage of the running system.
|build_type|: The BuildType of the running system.
|version|: The version of the running system. The use of this field is
system-specific. For example on Fuchsia a possible value for |version| is
"20190220_01_RC00".
|experiment_ids|: A list of experiments that are active on the device.
void SetAppVersion (const std::string & app_version)Resets the current app version. Do not set this field if Cobalt runs as a service.
void SetChannel (std::optional<std::string> channel)Resets the current channel value.
void ResetInternalMetrics (logger::InternalMetrics * internal_metrics)void OnChange (std::function<void ()> callback)void OverrideSystemProfile (const SystemProfile & profile)Overrides the stored SystemProfile. Useful for testing.
void FilteredSystemProfile (const ReportDefinition & report, const SystemProfile & profile_in, SystemProfile * profile_out)Filters a SystemProfile to only the SystemProfileFields in the given ReportDefinition.
