Recursively decodes Typhoeus
encoded arrays in given Hash.
@param hash [Hash]. This Hash will be modified!
@return [Hash] Hash with properly decoded nested arrays.

If the Hash is an array encoded by typhoeus an array is returned else the self is returned
@param hash [Hash] The Hash to convert into an Array.
@return [Arraya/Hash]
# File lib/rack/typhoeus/middleware/params_decoder/helper.rb, line 65 def convert(hash) if encoded?(hash) hash.sort{ |a, b| a[0].to_i <=> b[0].to_i }.map{ |key, value| value } else hash end end

Checks if Hash is an Array encoded as a Hash. Specifically will check for the Hash to have this form: {'0' => v0, '1' => v1, .., 'n' => vN }
@param hash [Hash]
@return [Boolean] True if its a encoded Array, else false.
# File lib/rack/typhoeus/middleware/params_decoder/helper.rb, line 49 def encoded?(hash) return false if hash.empty? if hash.keys.size > 1 keys = hash.keys.map{|i| i.to_i if i.respond_to?(:to_i)}.sort keys == hash.keys.size.times.to_a else hash.keys.first =~ /0/ end end
