after

Allows processing the return value of a handler method and the request/response objects.

The value returned by the REST API will be the value returned by the last @after handler, which allows to post process the results of the handler method.

Writing to the response body from within the specified handler function causes any further processing of the request ot be skipped, including any other @after annotations and writing the result value.
