Method Detail

postProcess

public flex.messaging.messages.Message postProcess(MessageProcessingContext context,
                                          flex.messaging.messages.Message inputMessage,
                                          flex.messaging.messages.Message outputMessage)

Hook for post-processing the outgoing AMF Message

Specified by:

postProcess in interface MessageInterceptor

Parameters:

context - context for the current request

inputMessage - the incoming AMF message

outputMessage - the outgoing AMF message

Returns:

the AMF message to send in response

preProcess

public flex.messaging.messages.Message preProcess(MessageProcessingContext context,
                                         flex.messaging.messages.Message inputMessage)

Hook for pre-processing the incoming AMF Message

Specified by:

preProcess in interface MessageInterceptor

Parameters:

context - context for the current request

inputMessage - the incoming AMF message

Returns:

the AMF message to process in the current request

getAuthenticationResult

protected Object getAuthenticationResult()

Converts the current Authentication object into a format suitable for AMF serialization back to the calling client.

This is an intended extension point for providing a custom conversion strategy, for example, to additionally provide information from a UserDetails object. The default implementation calls AuthenticationResultUtils.getAuthenticationResult() to convert the Authentication into a simple Map of the user's principal and granted authorities. A more ambitious implementation might map onto a custom domain object for which there is a parallel ActionScript object on the client.

To provide such a custom strategy, one would extend this class and replace the default implementation in the MessageInterceptor chain by utilizing the position attribute of the message-interceptor configuration tag.

Returns:

pertinent details of the currently authenticated user
