def ==(other)
  other.is_a?( EventType ) &&

  @event_class == other.event_class

   named_types = @event_class.attributes.map  {|key,type| "#{key} #{type.format}" }
   "#{@event_name} event(#{named_types.join(',')})" 
end

#mut? ⇒ Boolean

note: mut? == true MUST use new_zero (dup)

mut? == false MUST use zero (frozen/shared/singelton)

Returns:

  • (Boolean)
