Type scheduling_purpose

fd::scheduling_purpose — Denote what purpose a schedule serves or the context of scheduling.

Synopsis

// In header: <fd/functional.h>


enum scheduling_purpose { application_uptime = = 1, task_execution = = 2 };

Description

Some algorithms can make useful decisions knowing what purpose a schedule serves, or in other words, which context a schedule is used in.

application_uptime

The main objective is to define uptimes using 'fixed duration' schedules, possibly using 'action' schedules for intermittent events. To put it in more abstract terms: 'fixed duration' schedules are executive, 'action' schedules subordinate. E.g.: schedule uptime of a perpetually running program, using 'fixed duration' schedules; 'action' schedules might be for restarting.

task_execution

The main objective is to execute tasks using 'action' schedules, possibly using 'fixed duration' schedules for limiting execution times. To put it in more abstract terms: 'action' schedules are executive, 'fixed duration' schedules subordinate. E.g.: schedule execution of a self-completing task, using 'action' schedules; 'fixed duration' schedules limit the execution action to a specific uptime.
