Example 1 with ViewRenderer

use of com.vaadin.flow.router.legacy.ViewRenderer in project flow by vaadin.

the class ViewRendererTest method testViewInstantiationCustomization.

@Test
public void testViewInstantiationCustomization() {
    // override default implementation of reusing the views if possible
    ViewRenderer renderer = new TestViewRenderer(TestView.class, ParentView.class) {

        @Override
        protected <T extends View> T getView(Class<T> viewType, NavigationEvent event) {
            // always return a new view
            return ReflectTools.createInstance(viewType);
        }
    };
    renderer.handle(dummyEvent);
    View view1 = dummyEvent.getUI().getInternals().getActiveViewChain().get(0);
    View parentView1 = dummyEvent.getUI().getInternals().getActiveViewChain().get(1);
    renderer.handle(dummyEvent);
    View view2 = dummyEvent.getUI().getInternals().getActiveViewChain().get(0);
    View parentView2 = dummyEvent.getUI().getInternals().getActiveViewChain().get(1);
    Assert.assertNotSame(view1, view2);
    Assert.assertNotSame(parentView1, parentView2);
}
