Puppet Function: length

Defined in:
lib/puppet/functions/length.rb
Function type:
Ruby 4.x API

Overview

length(Variant[String,Array,Hash] $value) ⇒ Any

A function to eventually replace the old size() function for stdlib - The original size function did not handle Puppets new type capabilities, so this function is a Puppet 4 compatible solution.
