Module: OodCore::Job::Adapters::Flux::JobId Private

Defined in:
lib/ood_core/job/adapters/flux/job_id.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Convert Flux job ids to decimal. Flux prints ids in F58 (RFC 19), base58 with a "ƒ" prefix; OnDemand stores and returns them in decimal.

Written in the compact form so this file never reopens class Flux. It is required from inside the Flux class body, after the class exists.
