Define methods that retrieve the value from an initialized instance variable Hash, using the attribute as a key
@param attrs [Array, Set, Symbol]
# File lib/twitter/base.rb, line 8 def self.attr_reader(*attrs) mod = Module.new do attrs.each do |attribute| define_method attribute do @attrs[attribute.to_sym] end define_method "#{attribute}?" do !!@attrs[attribute.to_sym] end end end const_set(:Attributes, mod) include mod end
Retrieves an object from the identity map.
@param attrs [Hash] @return [Twitter::Base]

Returns a new object based on the response hash
@param response [Hash] @return [Twitter::Base]
