Interface JaasAuthenticationCallbackHandler

All Known Implementing Classes:

JaasNameCallbackHandler, JaasPasswordCallbackHandler

public interface JaasAuthenticationCallbackHandler

The JaasAuthenticationCallbackHandler is similar to the javax.security.auth.callback.CallbackHandler interface in that it defines a handle method. The JaasAuthenticationCallbackHandler is only asked to handle one Callback instance at at time rather than an array of all Callbacks, as the javax... CallbackHandler defines.

Before a JaasAuthenticationCallbackHandler is asked to 'handle' any callbacks, it is first passed the Authentication object that the login attempt is for. NOTE: The Authentication object has not been 'authenticated' yet.
