class Puppet::Provider::Confine::Variable

Require a specific value for a variable, either a Puppet setting or a Facter value. This class is a bit weird because the name is set explicitly by the ConfineCollection class – from this class, it’s not obvious how the name would ever get set.

Attributes

name[RW]

This is set by ConfineCollection.

Public Class Methods

Calls superclass method Puppet::Provider::Confine.new

# File lib/puppet/provider/confine/variable.rb, line 24
def initialize(values)
  super
  @values = @values.collect { |v| v.to_s.downcase }
end

summarize(confines) click to toggle source

Provide a hash summary of failing confines – the key of the hash is the name of the confine, and the value is the missing yet required values. Only returns failed values, not all required values.

# File lib/puppet/provider/confine/variable.rb, line 11
def self.summarize(confines)
  result = Hash.new { |hash, key| hash[key] = [] }
  confines.inject(result) { |total, confine| total[confine.name] += confine.values unless confine.valid?; total }
end
