Examples of ratpack.handling.Handler

ratpack.handling.Handler
sponder may just return a response to the client… class SimpleHandler implements Handler { void handle(Context exchange) { exchange.getResponse().send("Hello World!"); } } // A responder may add a response header, before delegating to the next in the pipeline… class DecoratingHandler implements Handler { void handle(Context exchange) { exchange.getResponse().getHeaders().set("Cache-Control", "no-cache"); exchange.next(); } } // Or a handler may conditionally respond… class ConditionalHandler implements Handler { void handle(Context exchange) { if (exchange.getRequest().getPath().equals("foo")) { exchange.getResponse().send("Hello World!"); } else { exchange.next(); } } } // A handler does not need to participate in the response, but can instead "route" the exchange to different handlers… class RoutingHandler implements Handler { private final Handler[] fooHandlers; public RoutingHandler(Handler... fooHandlers) { this.fooHandlers = fooHandlers; } void handle(Context exchange) { if (exchange.getRequest().getPath().startsWith("foo/")) { exchange.insert(fooHandlers); } else { exchange.next(); } } } // It can sometimes be appropriate to directly delegate to a handler, instead of using exchange.insert() … class FilteringHandler implements Handler { private final Handler nestedHandler; public FilteringHandler(Handler nestedHandler) { this.nestedHandler = nestedHandler; } void handle(Context exchange) { if (exchange.getRequest().getPath().startsWith("foo/")) { nestedHandler.handle(exchange); } else { exchange.next(); } } } @see Handlers @see Chain @see ratpack.registry.Registry
