Examples of org.apache.tapestry5.services.ComponentEventResultProcessor

org.apache.tapestry5.services.ComponentEventResultProcessor
Responsible for handling the return value provided by a component event handler method.
There are two services built into Tapestry that implement this interface: ComponentEventResultProcessor (used for ordinary page-oriented requests, and distinguished by the @ {@link org.apache.tapestry5.services.Traditional}and/or @ {@link org.apache.tapestry5.ioc.annotations.Primary} marker annotations) and AjaxComponentEventResultProcessor, used for Ajax requests (which typically return a partially rendered page), distinguished by the @ {@link org.apache.tapestry5.services.Ajax} marker annotation. @param < T>
