53 * Currently each scheme has only one instance of me,
54 * but this may change.
56 * This class is treated like a ref counted class.

80 * new decode API: virtual factory pattern
82 * Responsible for decoding the passed authentication header, creating or
83 * linking to a AuthUser object and for storing any needed details to complete
