public interface Renderable

A renderable object, that can be given to Context.render(Object).

A Renderer for this type is provided by Ratpack core, that simply delegates to render(Context). An alternative to providing a Renderer implementation for a type is to make the type implement this interface.

 import ratpack.core.handling.Context;
 import ratpack.core.render.Renderable;
 import ratpack.test.embed.EmbeddedApp;

 import static org.junit.jupiter.api.Assertions.*;

 public class Example {
   static class Thing implements Renderable {
     public void render(Context context) {
       context.render("thing!");
     }
   }

   static void main(String... args) throws Exception {
     EmbeddedApp.fromHandler(ctx ->
       ctx.render(new Thing())
     ).test(httpClient ->
       assertEquals("thing!", httpClient.getText())
     );
   }
 }
 

An alternative to making a type implement this interface, is implementing a Renderer for it.
