class Oj::EasyHash - Oj

# 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.

### Public Class Methods

Initializes the instance to an empty Hash.

### Public Instance Methods

    # File lib/oj/easy_hash.rb, line 24
    def [](key)
      return fetch(key, nil) if has_key?(key)
      return fetch(key.to_s, nil) if has_key?(key.to_s)
      fetch(key.to_sym, nil)
    end

method_missing(m, *args, &block) click to toggle source

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)
      if m.to_s.end_with?('=')
        raise ArgumentError.new("wrong number of arguments (#{args.size} for 1 with #{m}) to method #{m}") if args.nil? or 1 != args.length
        m = m[0..-2]
        return store(m.to_s, args[0]) if has_key?(m.to_s)
        return store(m.to_sym, args[0]) if has_key?(m.to_sym)
        return store(m, args[0])
      else
        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)
      end
      raise NoMethodError.new("undefined method #{m}", m)
    end

respond_to?(m) click to toggle source

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

    # File lib/oj/easy_hash.rb, line 17
    def respond_to?(m)
      return true if super
      return true if has_key?(key)
      return true if has_key?(key.to_s)
      has_key?(key.to_sym)
    end
