Public Member Functions
constexpr	Settings (std::chrono::milliseconds period, utils::Flags< Flags > flags={}, logging::Level span_level=logging::Level::kInfo)
constexpr	Settings (std::chrono::milliseconds period, std::chrono::milliseconds distribution, utils::Flags< Flags > flags={}, logging::Level span_level=logging::Level::kInfo)

template<class Rep , class Period >
constexpr	Settings (std::chrono::duration< Rep, Period > period)

Public Attributes
std::chrono::milliseconds	period {}
	Period for the task execution. Task is repeated every (period +/- distribution) - time of previous execution
std::chrono::milliseconds	distribution {}
	Jitter for task repetitions. If kChaotic is set in flags the task is repeated every (period +/- distribution) - time of previous execution
std::optional< std::chrono::milliseconds >	exception_period
	Used instead of period in case of exception, if set.
utils::Flags< Flags >	flags {}
	Flags that control the behavior of PeriodicTask.
logging::Level	span_level {logging::Level::kInfo}
	tracing::Span that measures each execution of the task uses this logging level.
engine::TaskProcessor *	task_processor {nullptr}
	TaskProcessor to execute the task. If nullptr then the PeriodicTask::Start() calls engine::current_task::GetTaskProcessor() to get the TaskProcessor.

Static Public Attributes
static constexpr uint8_t	kDistributionPercent = 25

Member Data Documentation

distribution

std::chrono::milliseconds utils::PeriodicTask::Settings::distribution {}

Jitter for task repetitions. If kChaotic is set in flags the task is repeated every (period +/- distribution) - time of previous execution

Definition at line 103 of file periodic_task.hpp.

exception_period

std::optional<std::chrono::milliseconds> utils::PeriodicTask::Settings::exception_period

Used instead of period in case of exception, if set.

Definition at line 106 of file periodic_task.hpp.

flags

utils::Flags<Flags> utils::PeriodicTask::Settings::flags {}

Flags that control the behavior of PeriodicTask.

Definition at line 109 of file periodic_task.hpp.

kDistributionPercent

constexpr uint8_t utils::PeriodicTask::Settings::kDistributionPercent = 25

staticconstexpr

Definition at line 60 of file periodic_task.hpp.

period

std::chrono::milliseconds utils::PeriodicTask::Settings::period {}

Period for the task execution. Task is repeated every (period +/- distribution) - time of previous execution

Definition at line 98 of file periodic_task.hpp.

span_level

logging::Level utils::PeriodicTask::Settings::span_level {logging::Level::kInfo}

tracing::Span that measures each execution of the task uses this logging level.

Definition at line 113 of file periodic_task.hpp.

task_processor

engine::TaskProcessor* utils::PeriodicTask::Settings::task_processor {nullptr}

TaskProcessor to execute the task. If nullptr then the PeriodicTask::Start() calls engine::current_task::GetTaskProcessor() to get the TaskProcessor.
