Class: Unicron::Schedule

Inherits:

Object

• Object
• Unicron::Schedule

Defined in:

lib/unicron/schedule.rb

Overview

Schedule manages a JobQueue which contains Job instances, and a thread which pops and executes them. For simplicity’s sake, the Unicron module manages a default Schedule, but you can create and manage your own if necessary. Each uses its own JobQueue and thread, so they will not interfere with each other.

Instance Method Summary

• #<<(job) ⇒ Object

  Add a Job to the Schedule’s JobQueue.

• #initialize ⇒ Schedule constructor

  Create a new, empty Schedule.

• #schedule(options = {}, &block) ⇒ Object

  Create a new Job and add it to the Schedule.
