Public Class Methods

create(hash) { |key| ... } click to toggle source

Creates an OpenStruct from the given hash

It recursively transform nested hashes into OpenStruct
It recursively goes through arrays, transforming hashes into OpenStruct
An optional block can be passed to process the hash keys

# File lib/open_struct_factory.rb, line 9
def self.create(hash, &block) # :yields: key
  properties = {}
  hash.each_pair do |key, value|
    property_name = block_given? ? (yield key) : key
    properties[property_name] = process_value(value, &block)
  end
  OpenStruct.new(properties)
end
