grails.core.GrailsApplication

The main interface representing a running Grails application. This interface's main purpose is to provide a mechanism for analysing the conventions within a Grails application as well as providing metadata and information about the execution environment.
The GrailsApplication interface interfacts with {@link ArtefactHandler} instanceswhich are capable of analysing different artefact types (controllers, domain classes etc.) and introspecting the artefact conventions
Implementors of this inteface should be aware that a GrailsApplication is only initialised when the initialise() method is called. In other words GrailsApplication instances are lazily initialised by the Grails runtime. @see #initialise() @see ArtefactHandler @author Graeme Rocher @author Steven Devijver @since 0.1

    private GrailsApplicationAttributes getAttributesForClasses(Class<?>[] classes, GroovyClassLoader gcl) {
        MockApplicationContext context = new MockApplicationContext();
        MockServletContext servletContext = new MockServletContext();
        servletContext.setAttribute(GrailsApplicationAttributes.APPLICATION_CONTEXT,context);


        GrailsApplication app = new DefaultGrailsApplication(classes,gcl);
        app.initialise();
        context.registerMockBean(GrailsApplication.APPLICATION_ID,app);


        GrailsClass[] controllers = app.getArtefacts(ControllerArtefactHandler.TYPE);
        for (int i = 0; i < controllers.length; i++) {
            context.registerMockBean(controllers[i].getFullName(), controllers[i].newInstance());
        }


        GrailsClass[] taglibs = app.getArtefacts(TagLibArtefactHandler.TYPE);
