Class Detail

myfaces._impl.xhrCore._AjaxResponse()

This singleton is responsible for handling the standardized xml ajax response Note: since the semantic processing can be handled about 90% in a functional style we make this class stateless. Every state information is stored temporarily in the context. The singleton approach also improves performance due to less object gc compared to the old instance approach.
