class Oj::EasyHash
A Hash subclass that normalizes the hash keys to allow lookup by the key.to_s or key.to_sym. It also supports looking up hash values by methods that match the keys.

Handles requests for Hash values. Others cause an Exception to be raised. @param [Symbol|String] m method symbol @return [Boolean] the value of the specified instance variable. @raise [ArgumentError] if an argument is given. Zero arguments expected. @raise [NoMethodError] if the instance variable is not defined.
# File lib/oj/easy_hash.rb, line 35 def method_missing(m, *args, &block) raise ArgumentError.new("wrong number of arguments (#{args.size} for 0 with #{m}) to method #{m}") unless args.nil? or args.empty? return fetch(m, nil) if has_key?(m) return fetch(m.to_s, nil) if has_key?(m.to_s) return fetch(m.to_sym, nil) if has_key?(m.to_sym) raise NoMethodError.new("undefined method #{m}", m) end
respond_to?(m)

Replaces the Object.respond_to?() method. @param [Symbol] m method symbol @return [Boolean] true for any method that matches an instance
variable reader, otherwise false.
Calls superclass method
