Object
A generic class that is used only for storing attributes. It is the base Class for auto-generated classes in the storage system. Instance variables are added using the instance_variable_set() method. All instance variables can be accessed using the variable name (without the @ prefix). No setters are provided as the Class is intended for reading only.
Define a new class based on the Oj::Bag class. This is used internally in the Oj module and is available to service wrappers that receive XML requests that include Objects of Classes not defined in the storage process. @param [String] classname Class name or symbol that includes Module names. @return [Object] an instance of the specified Class. @raise [NameError] if the classname is invalid.
# File lib/oj/bag.rb, line 63 def self.define_class(classname) classname = classname.to_s unless classname.is_a?(String) tokens = classname.split('::').map(&:to_sym) raise NameError.new("Invalid classname '#{classname}") if tokens.empty? m = Object tokens[0..-2].each do |sym| if m.const_defined?(sym) m = m.const_get(sym) else c = Module.new m.const_set(sym, c) m = c end end sym = tokens[-1] if m.const_defined?(sym) c = m.const_get(sym) else c = Class.new(Oj::Bag) m.const_set(sym, c) end c end
The initializer can take multiple arguments in the form of key values where the key is the variable name and the value is the variable value. This is intended for testing purposes only. @example Oj::Bag.new(:@x => 42, :@y => 57) @param [Hash] args instance variable symbols and their values
# File lib/oj/bag.rb, line 16 def initialize(args = {}) args.each do |k,v| self.instance_variable_set(k, v) end end
Replaces eql?() with something more reasonable for this Class. @param [Object] other Object to compare self to @return [Boolean] true if each variable and value are the same, otherwise false.
# File lib/oj/bag.rb, line 47 def eql?(other) return false if (other.nil? or self.class != other.class) ova = other.instance_variables iv = instance_variables return false if ova.size != iv.size iv.all? { |vid| instance_variable_get(vid) != other.instance_variable_get(vid) } end
Handles requests for variable values. Others cause an Exception to be raised. @param [Symbol] 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/bag.rb, line 37 def method_missing(m, *args, &block) raise ArgumentError.new("wrong number of arguments (#{args.size} for 0) to method #{m}") unless args.nil? or args.empty? at_m = :"@#{m}" raise NoMethodError.new("undefined method #{m}", m) unless instance_variable_defined?(at_m) instance_variable_get(at_m) end
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.
# File lib/oj/bag.rb, line 26 def respond_to?(m) return true if super instance_variables.include?(:"@#{m}") end
