## [Java] Class DelegatingScript

- groovy.util.DelegatingScript

-     public abstract class DelegatingScript
      extends Script

  Script that performs method invocations and property access like Closure does.

  DelegatingScript is a convenient basis for loading a custom-defined DSL as a Script, then execute it. The following sample code illustrates how to do it:

       class MyDSL {
           public void foo(int x, int y, Closure z) { ... }
           public void setBar(String a) { ... }
       }

       CompilerConfiguration cc = new CompilerConfiguration();
       cc.setScriptBaseClass(DelegatingScript.class.getName());
       GroovyShell sh = new GroovyShell(cl,new Binding(),cc);
       DelegatingScript script = (DelegatingScript)sh.parse(new File("my.dsl"))
       script.setDelegate(new MyDSL());
       script.run();

  `my.dsl` can look like this:

       foo(1,2) {
           ....
       }
       bar = ...;

  DelegatingScript does this by delegating property access and method invocation to the `delegate` object.

  More formally speaking, given the following script:

       a = 1;
       b(2);

  Using DelegatingScript as the base class, the code will run as:

       delegate.a = 1;
       delegate.b(2);

  ... whereas in plain Script, this will be run as:

       binding.setProperty("a",1);
       ((Closure)binding.getProperty("b")).call(2);
