java.lang.Object

com.amazon.ask.dispatcher.impl.DefaultRequestDispatcher

All Implemented Interfaces:

RequestDispatcher

public class DefaultRequestDispatcher
extends Object
implements RequestDispatcher

This implementation routes incoming requests to a RequestMapper to find a RequestHandlerChain. A HandlerAdapter is used to execute the discovered request handler type. RequestInterceptor and ResponseInterceptor instances may be configured globally on this dispatcher to be executed for all requests. Interceptors set on the RequestHandlerChain level are also supported. An ExceptionMapper is used to find exception handlers in the event of an unhandled exception during request processing.
