Callback

javax.security.auth.callback.Callback

Known Indirect Subclasses

AuthorizeCallback, ChoiceCallback, ConfirmationCallback, LanguageCallback, NameCallback, PasswordCallback, RealmCallback, RealmChoiceCallback, TextInputCallback, TextOutputCallback

AuthorizeCallback	This callback is used by `SaslServer` to determine whether one entity (identified by an authenticated authentication id) can act on behalf of another entity (identified by an authorization id).
ChoiceCallback	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	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	Underlying security services instantiate and pass a `LanguageCallback` to the `handle` method of a `CallbackHandler` to retrieve the `Locale` used for localizing text.
NameCallback	Underlying security services instantiate and pass a `NameCallback` to the `handle` method of a `CallbackHandler` to retrieve name information.
PasswordCallback	Underlying security services instantiate and pass a `PasswordCallback` to the `handle` method of a `CallbackHandler` to retrieve password information.
RealmCallback	This callback is used by `SaslClient` and `SaslServer` to retrieve realm information.
RealmChoiceCallback	This callback is used by `SaslClient` and `SaslServer` to obtain a realm given a list of realm choices.
TextInputCallback	Underlying security services instantiate and pass a `TextInputCallback` to the `handle` method of a `CallbackHandler` to retrieve generic text information.
TextOutputCallback	Underlying security services instantiate and pass a `TextOutputCallback` to the `handle` method of a `CallbackHandler` to display information messages, warning messages and error messages.

Class Overview

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.

Callback implementations do not retrieve or display the information requested by underlying security services. Callback implementations simply provide the means to pass such requests to applications, and for applications, if appropriate, to return requested information back to the underlying security services.
