Class GroovyChainAction

java.lang.Object

ratpack.groovy.handling.GroovyChainAction

All Implemented Interfaces:

Action<Chain>, GroovyChain, Chain

public abstract class GroovyChainAction
extends java.lang.Object
implements GroovyChain, Action<Chain>

A convenience super class for a standalone implementation of a Action<GroovyChain>.

Subclasses implement the execute() method, and implicitly program against the GroovyChain DSL.

import ratpack.groovy.handling.GroovyChainAction
 import ratpack.groovy.test.embed.GroovyEmbeddedApp

 class Handlers extends GroovyChainAction {
   public void execute() throws Exception {
     path { render "root" }
     prefix("foo") {
       path("bar") { render "foobar" }
     }
   }
 }

 GroovyEmbeddedApp.of {
   handlers new Handlers()
 } test {
   assert getText() == "root"
   assert getText("foo/bar") == "foobar"
 }
