Overview

:title: EnumeratedType

EnumeratedType lets you create enumerated types like this:

class OutputType < EnumeratedType
  AUTODETECT
  UNKNOWN
  NOSOUND
  WAVWRITER
  DSOUND
  WINMM
  ASIO
  OSS
  ALSA
  ESD
  SOUNDMANAGER
  COREAUDIO
  XBOX
  PS2
  GC
  XBOX360
  PSP
end

If you want to start with a different integer than 0, you can just do:

class OutputType < EnumeratedType
  start 15
  AUTODETECT
  ...
end

You can also use start anywhere in the list, to have subsequent constants enumerated starting with the given value.
