## Interface ComponentEventRequestHandler

- All Known Implementing Classes:
    `AjaxComponentEventRequestHandler`, `ComponentEventRequestHandlerImpl`

      @UsesOrderedConfiguration(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.
