[nanocontainer-scm] [jira] Created: (NANO-138) Be able to access ComponentAdapter in Groovy Builder

Be able to access ComponentAdapter in Groovy Builder
----------------------------------------------------

         Key: NANO-138
         URL: http://jira.codehaus.org/browse/NANO-138
     Project: NanoContainer
        Type: Wish
  Components: core  
    Versions: 1.0-beta-5    
    Reporter: Michael Rimov


Currently, it doesn't appear possible to access a ComponentAdapter from within the Groovy builder syntax.  The following test case illustrates an 'ideal' for modifying the component adapter.  Of course, I'd be happy to do it nearly any way using the builder syntax. :)

    public void testBuildWithComponentAdapter() {
        Reader script = new StringReader(""
            + "import java.text.SimpleDateFormat;\n"
            + "import com.genfw.core.container.BeanNanoDecorator;\n"
            + "import org.picocontainer.defaults.*\n"
            + "\n"
            + "builder = new org.nanocontainer.script.groovy.NanoContainerBuilder(new BeanNanoDecorator())\n"
            + "pico = builder.container() { \n"
            + "  component([ class: SimpleDateFormat) {\n"
            + "       //If ComponentAdapter was returned -- then modification would be possible."
            + "       properties([\"lenient\":false, \"2DigitYearStart\":new Date(0)\n]]])\n" 
            + "   }\n"
            + "}");

        ObjectReference predefined = new SimpleReference();
        predefined.set(new DefaultPicoContainer(new BeanPropertyComponentAdapterFactory(new DefaultComponentAdapterFactory())));

        ScriptedContainerBuilder builder = new GroovyContainerBuilder(script, Thread.currentThread().getContextClassLoader());
        builder.buildContainer(predefined,null,null, false);
        PicoContainer rootContainer = (PicoContainer)predefined.get();

        assertNotNull(rootContainer);
        assertNotNull(rootContainer.getComponentAdapter(SimpleDateFormat.class));
        assertEquals(BeanPropertyComponentAdapter.class,  rootContainer.getComponentAdapter(SimpleDateFormat.class).getClass());

        SimpleDateFormat dateFormat = (SimpleDateFormat)rootContainer.getComponentInstance(SimpleDateFormat.class);
        assertNotNull(dateFormat);
        
        //Currently fails
        //assertEquals(false, dateFormat.isLenient());
        //assertEquals(new Date(0), dateFormat.get2DigitYearStart());

    }
