详细描述

Non-constructible utility struct providing task scheduling primitives.

Contains Config, Status, RetStatus, process() and process_with_ret(). Users interact with this struct primarily via MessageLoop::exec_task().

成员类型定义说明

Callback

using vlink::Schedule::Callback = std::function<void()>

Callback type for void tasks and lifecycle hooks (schedule/execution timeout, else).

CatchCallback

using vlink::Schedule::CatchCallback = std::function<void(std::exception&)>

Callback type invoked when an exception is caught inside the task.

RetCallback

using vlink::Schedule::RetCallback = std::function<bool()>

Callback type for tasks that return a boolean result.

构造及析构函数说明

Schedule() [1/3]

vlink::Schedule::Schedule ( )

delete

这是这个函数的调用关系图:

Schedule() [2/3]

vlink::Schedule::Schedule ( const Schedule & )

delete

函数调用图:

Schedule() [3/3]

vlink::Schedule::Schedule ( Schedule && )

delete

成员函数说明

operator=() [1/2]

Schedule & vlink::Schedule::operator= ( const Schedule & )

delete

函数调用图:

operator=() [2/2]

Schedule & vlink::Schedule::operator= ( Schedule && )

delete

函数调用图:

process()

Status vlink::Schedule::process ( const Config & config, Callback && callback, Callback & wrapper_callback )

staticnodiscard

Wraps a void callback in a Config envelope and produces a wrapper task.

Called internally by MessageLoop::exec_task(). Creates the Status and populates wrapper_callback with the task wrapper ready to be posted to the queue.

参数

config	Scheduling configuration.
callback	Void callable to execute.
wrapper_callback	Output: the wrapped task to be posted.

返回

Status handle for chaining callbacks.

这是这个函数的调用关系图:

process_with_ret()

RetStatus vlink::Schedule::process_with_ret ( const Config & config, RetCallback && callback, Callback & wrapper_callback )

staticnodiscard

Wraps a bool-returning callback in a Config envelope and produces a wrapper task.

Called internally by MessageLoop::exec_task(). Creates the RetStatus and populates wrapper_callback with the task wrapper ready to be posted to the queue.

参数

config	Scheduling configuration.
callback	Bool-returning callable to execute.
wrapper_callback	Output: the wrapped task to be posted.

返回

RetStatus handle for chaining callbacks.
