Callback View Source	Implementations of this interface are passed to a `CallbackHandler`, allowing underlying security services the ability to interact with a calling application to retrieve specific authentication data such as usernames and passwords, or to display certain information, such as error and warning messages.
CallbackHandler View Source	An application implements a `CallbackHandler` and passes it to underlying security services so that they may interact with the application to retrieve specific authentication data, such as usernames and passwords, or to display certain information, such as error and warning messages.
ChoiceCallback View Source	Underlying security services instantiate and pass a `ChoiceCallback` to the `handle` method of a `CallbackHandler` to display a list of choices and to retrieve the selected choice(s).
ConfirmationCallback View Source	Underlying security services instantiate and pass a `ConfirmationCallback` to the `handle` method of a `CallbackHandler` to ask for YES/NO, OK/CANCEL, YES/NO/CANCEL or other similar confirmations.
LanguageCallback View Source	Underlying security services instantiate and pass a `LanguageCallback` to the `handle` method of a `CallbackHandler` to retrieve the `Locale` used for localizing text.
NameCallback View Source	Underlying security services instantiate and pass a `NameCallback` to the `handle` method of a `CallbackHandler` to retrieve name information.
PasswordCallback View Source	Underlying security services instantiate and pass a `PasswordCallback` to the `handle` method of a `CallbackHandler` to retrieve password information.
TextInputCallback View Source	Underlying security services instantiate and pass a `TextInputCallback` to the `handle` method of a `CallbackHandler` to retrieve generic text information.
TextOutputCallback View Source	Underlying security services instantiate and pass a `TextOutputCallback` to the `handle` method of a `CallbackHandler` to display information messages, warning messages and error messages.
UnsupportedCallbackException View Source	Signals that a `CallbackHandler` does not recognize a particular `Callback`.
