Documentation for Enum::Value

Enum::Value

What it does

Enum::Value lets you create immutable value object instances from your Enum::Base subclasses. These Value instances delegate to the Enum::Base subclass for all read and write operations. Additionally, these instances are comparable with each other AND with strings, symbols, and integers (the integers representing enum indexes).

Simple setup

class Side < Enum::Base

values :left, :right, :whole

Get structured array of hashes of memcached keys on multiple servers
#!/usr/bin/env ruby
# List all keys stored in memcache.
# Forked from bkimble's gist https://gist.github.com/bkimble/1365005
# Credit to Graham King at http://www.darkcoding.net/software/memcached-list-all-keys/ for the original article on how to get the data from memcache in the first place.
# Currently resides at https://gist.github.com/ginjo/aaa4a4395fcdbbad3d29

# This fork separates the server query code from results presentation.
# The primary function of this script is to return an array of hashes of
# key items from any number of provided memcached servers.
