Detailed Description

Class implementation of condition variable

A condition variable isn't really a variable. It's a list of threads.

The design here is that a basic_convar_task "waits", and a condition_variable "signals". This affects where the public interfaces reside.

Constructor & Destructor Documentation

◆ basic_condition_variable()

mn::ext::basic_condition_variable::basic_condition_variable ( )

Constructor to create a condition variable.

Member Function Documentation

◆ add_list()

void mn::ext::basic_condition_variable::add_list ( basic_convar_task * thread )

private

Internal helper function to queue a basic_convar_task to this condition_variable's wait list.

Parameters

thread The basic_convar_task to add to the waiting list

◆ broadcast()

void mn::ext::basic_condition_variable::broadcast ( )

Signal all threads waiting on this condition_variable.

◆ notify_all()

void mn::ext::basic_condition_variable::notify_all ( )

inlinenoexcept

◆ notify_one()

void mn::ext::basic_condition_variable::notify_one ( )

inlinenoexcept

◆ signal()

void mn::ext::basic_condition_variable::signal ( )

Signal a thread waiting on this condition_variable (FIFO list).

The basic_convar_task class and the basic_condition_variable class are interdependent. If we allow the basic_convar_task class to access the internals of the basic_condition_variable, we can reduce the public interface which is a good thing.
