  @name          = array[1]
  @full_name     = array[2]
  @rw            = array[3]
  @visibility    = array[4]
  @comment       = array[5]

  #                      7 handled below
  @parent_name   = array[8]
  @parent_class  = array[9]
  @section_title = array[10]

  @file = array[7] if version > 1

  @parent_name ||= @full_name.split('#', 2).first
