* processing runtime.
* If the received message is a (mechanism-specific) meta-message,
* the method implementation must attempt to transform the meta-message
* into a corresponding mechanism-specific response message, or to the
* validated application request message.
* The runtime will bind a validated application message into the
* the corresponding service invocation.
* This method conveys the outcome of its message processing either
* by returning an AuthStatus value or by throwing an AuthException.
*
* @param messageInfo A contextual object that encapsulates the
* client request and server response objects, and that may be
* used to save state across a sequence of calls made to the
* methods of this interface for the purpose of completing a
* secure message exchange.
*
* @param clientSubject A Subject that represents the source of the
* service
* request. It is used by the method implementation to store
* Principals and credentials validated in the request.
*
* @param serviceSubject A Subject that represents the recipient of the
* service request, or null. It may be used by the method
* implementation as the source of Principals or credentials to
* be used to validate the request. If the Subject is not null,
* the method implementation may add additional Principals or
* credentials (pertaining to the recipient of the service
* request) to the Subject.
*
* @return An AuthStatus object representing the completion status of
* the processing performed by the method.
* The AuthStatus values that may be returned by this method
* are defined as follows:
*
*
* - AuthStatus.SUCCESS when the application request message
* was successfully validated. The validated request message is
* available by calling getRequestMessage on messageInfo.
*
*
- AuthStatus.SEND_SUCCESS to indicate that validation/processing
* of the request message successfully produced the secured application
* response message (in messageInfo). The secured response message is
* available by calling getResponseMessage on messageInfo.
*
*
- AuthStatus.SEND_CONTINUE to indicate that message validation is
* incomplete, and that a preliminary response was returned as the
* response message in messageInfo.
*
* When this status value is returned to challenge an
* application request message, the challenged request must be saved
* by the authentication module such that it can be recovered
* when the module's validateRequest message is called to process
* the request returned for the challenge.
*
*
- AuthStatus.SEND_FAILURE to indicate that message validation failed
* and that an appropriate failure response message is available by
* calling getResponseMessage on messageInfo.
*

* @exception AuthException When the message processing failed without
* establishing a failure response message (in messageInfo).
