module Sleepier

Sleepier is a Process Management tool in the style of a supervisor. It most similar to the Erlang supervisor behaviour.

The basic usage of Sleepier is:

Create an `Array` of `Sleepier::ChildSpec` objects
Initialize a `Sleepier::Supervisor` object with the array of `Sleepier::ChildSpec` objects
Create a new `Thread` and call `monitor` on the supervisor object within the thread
Call `start` on the supervisor

Note that `start` will return as soon as the processes are started, and does not wait for them to finish.

Features:

VALID_RESTART_OPTIONS

The different styles which can be used to manage restarts

:permanent - Always restart the process, except when it has been restarted more than `max_restart_count` times in `max_restart_window` seconds
:temporary - Never restart the process
:transient - Only restart the process if it failed and hasn't been restarted more than `max_restart_count` times in `max_restart_window` seconds

VALID_SHUTDOWN_OPTIONS

How to shutdown the process

:brutal_kill - Terminate immediately, without giving it a chance to terminate gracefully. Equivalent to a kill -9 on Linux
:timeout - Attempt to terminate gracefully, but after `shutdown_timeout` seconds, brutally kill
:infinity - Terminate gracefully, even if it takes forever. USE WITH CAUTION! THIS CAN RESULT IN NEVER-ENDING PROCESSES
