#from_response(data, encoding = 'UTF-8') ⇒ Object

Public - Decodes some JSON text in the receiver, and marshals it into a class specified in obj.

For instance:

class Stuff
  attr_reader :a, :b
  def initialize(values)
    @a = values['a']
    @b = values['b']
  end
end
thing = Stuff.from_response '{"a":42,"b":"foo"}'
thing.a == 42
thing.b == "foo"
