• Object
• Moneta::Transform
• Moneta::Transforms::Spread

Defined in:

lib/moneta/transforms/spread.rb

Overview

Transforms strings by inserting a “/” character after the first two characters, using File.join. This can be used with the Adapters::File adapter to spread files into subdirectories. The :HashFile option on Moneta.new uses this transform (in conjunction with MD5) - see README.

Examples:

transform = Moneta::Transforms::Spread.new
transform.encode('testing')  # => 'te/sting'
transform.encode('te/sting') # => 'te/sting'
transform.encode('tes/ting') # => 'te/s/ting'
