MOOSE/Moose Development/Moose/Tasking/Task_Manager.lua

--- **Tasking** - This module contains the TASK_MANAGER class and derived classes.
-- 
-- ===
-- 
-- 1) @{Tasking.Task_Manager#TASK_MANAGER} class, extends @{Core.Fsm#FSM}
-- ===
-- The @{Tasking.Task_Manager#TASK_MANAGER} class defines the core functions to report tasks to groups.
-- Reportings can be done in several manners, and it is up to the derived classes if TASK_MANAGER to model the reporting behaviour.
-- 
-- 1.1) TASK_MANAGER constructor:
-- -----------------------------------
--   * @{Tasking.Task_Manager#TASK_MANAGER.New}(): Create a new TASK_MANAGER instance.
-- 
-- 1.2) TASK_MANAGER reporting:
-- ---------------------------------
-- Derived TASK_MANAGER classes will manage tasks using the method @{Tasking.Task_Manager#TASK_MANAGER.ManageTasks}(). This method implements polymorphic behaviour.
-- 
-- The time interval in seconds of the task management can be changed using the methods @{Tasking.Task_Manager#TASK_MANAGER.SetRefreshTimeInterval}(). 
-- To control how long a reporting message is displayed, use @{Tasking.Task_Manager#TASK_MANAGER.SetReportDisplayTime}().
-- Derived classes need to implement the method @{Tasking.Task_Manager#TASK_MANAGER.GetReportDisplayTime}() to use the correct display time for displayed messages during a report.
-- 
-- Task management can be started and stopped using the methods @{Tasking.Task_Manager#TASK_MANAGER.StartTasks}() and @{Tasking.Task_Manager#TASK_MANAGER.StopTasks}() respectively.
-- If an ad-hoc report is requested, use the method @{Tasking.Task_Manager#TASK_MANAGER#ManageTasks}().
-- 
-- The default task management interval is every 60 seconds.
--
-- # Developer Note
-- 
-- Note while this class still works, it is no longer supported as the original author stopped active development of MOOSE
-- Therefore, this class is considered to be deprecated
