Detailed Description

An run context with execution information and is required for the read and write for Input and Output respectively.

An object of this class is passed to the callbacks of Control::step(), Control::enterPreOp(), Control::enterOperational(), Control::enterPostOp() and Control::final(). It provides information about the current execution, like the scheduled time, current stage and execution counter of the pipeline. This object is also passed to the Input::read() and Output::write() functions and provides errors information occurring during read and write operations. You never create objects of this class yourself. If you want to handle errors yourself, you can use the cleanRunContext() function to get your own RunContext for managing.

Constructor & Destructor Documentation

RunContext() [1/2]

xentara::RunContext::RunContext ( )

delete

No default construction.

RunContext() [2/2]

xentara::RunContext::RunContext ( const RunContext &  )

delete

Delete the copy constructor.

Member Function Documentation

counter()

auto xentara::RunContext::counter

(

)

const -> std::int64_t

Gets the execution counter of the trigger.

Returns

The number of times the trigger has been executed. On the first execution, 0 is returned.

currentStage()

auto xentara::RunContext::currentStage

(

)

const -> Stage

Gets the current stage of Xentara.

Returns

Stage from Stage enum

error()

auto xentara::RunContext::error

(

)

const -> std::error_code

Gets the error that occurred during read or write operations.

Returns

The corresponding error code

operator=()

auto xentara::RunContext::operator= ( const RunContext &  ) -> RunContext &=delete

delete

Delete the assignment operator.

resetError()

auto xentara::RunContext::resetError

(

)

-> void

Resets the error code.

scheduledTimestamp()

auto xentara::RunContext::scheduledTimestamp

(

)

const -> std::chrono::system_clock::time_point

Gets the time the pipeline was scheduled for.

Returns

The time the pipeline was scheduled for. This is not the actual time at the time the function is called, but the time that the pipeline was initially intended to run. For timers, this is the time that the timer was scheduled to run, and for events, the time that the event occurred.

setError()

auto xentara::RunContext::setError

(

std::error_code

error

)

-> void

Sets the error code with the provided value.

Note

passing std::error_code() will reset the error code.

xentaraSkillElement()

auto xentara::RunContext::xentaraSkillElement ( ) const & -> const skill::Element &

noexcept

Gets the Xentara skill element.

This function gives access to the control skill element in the Xentara.

Returns

A reference to the skill element
