public abstract class Processor
extends ChainedComponent

Superclass of chainable components processing Requests to create Responses.

Processors typically changes the Request and/or the Response. It may also make multiple forward requests, in series or parallel, or manufacture the response content itself or by calling an external service.

Typical usage: public class MyProcessor extends Processor { @Override public Response process(Request request, Execution execution) { // process the request here Response response = execution.process(request); // Pass along to get the Response // process (or fill in) Data/DataList items on the response here return response; } }
