Subject: How to iterate through instance attribute names (attr_accessor)

Say, I have a class:

class Event
  attr_accessor	:a,
                        :b,
                        :c,
                        :d

  def initialize()
  end

  def validate
    # validate all attributes at once here
  end

  protected

  def validate_a
    # a can be any number from 1-10 if b = 'Y' and c is blank
  end

  def validate_b
    # b can be 'Y' or 'N'
  end

  def validate_c
  end

  def validate_d
  end

end

And in method validate, I'd like to iterate through all the attributes
and run their respective validating method.  Is there a way for me to
be able to iterate through my list of attr_accessor symbols and
reference their names to know which method to call?

Thanks,
