Instance Method Details

#as_stored ⇒ Hash

Returns Hash with the keys as they were stored (before normalization).

Returns:

  • (Hash) —

    Hash with the keys as they were stored (before normalization).

def as_stored

end

#denormalize(key) ⇒ String

Returns the version of key as it was stored before normalization. If key isn't in the map, returns it as it was passed in.

Returns:

  • (String)
