Interface ComponentEventRequestHandler

All Known Implementing Classes:
AjaxComponentEventRequestHandler, ComponentEventRequestHandlerImpl

@UsesOrderedConfiguration(value=ComponentEventRequestFilter.class)
public interface ComponentEventRequestHandler

Handler interface for component event requests. Component event requests do things such as process a form submission or otherwise change state. In the majority of cases, after the component event, a redirect response is sent to the client which, in turn, causes a page render.

The ComponentEventRequestHandler service is a pipeline, allowing extensibility via contributed filters. It may be distinguished by the @Traditional marker annotation.

A second service, AjaxComponentEventRequestHandler is also a pipeline and may be distinguished by the @Ajax marker annotation.
