obj.methods    → array

Returns a list of the names of methods publicly accessible in obj. This will include all the methods accessible in obj’s ancestors.

class Klass
  def kMethod()
  end
end

                        "class", "instance_variable_set",
                         "methods", "extend", "__send__", "instance_eval"]
