# File lib/facter/custom_facts/util/confine.rb, line 22 def initialize(fact = nil, *values, &block) raise ArgumentError, 'The fact name must be provided' unless fact || block_given? raise ArgumentError, 'One or more values or a block must be provided' if values.empty? && !block_given? @fact = fact @values = values @block = block end
Add the restriction. Requires the fact name, an operator, and the value we’re comparing to.
@param fact [Symbol] Name of the fact @param values [Array] One or more values to match against.
They can be any type that provides a === method.
@param block [Proc] Alternatively a block can be supplied as a check. The fact
value will be passed as the argument to the block. If the block returns true then the fact will be enabled, otherwise it will be disabled.

Evaluate the fact, returning true or false. if we have a block parameter then we only evaluate that instead
