示例1: testInstantiateChain

import com.espertech.esper.view.std.LastElementView; //導入依賴的package包/類
public void testInstantiateChain() throws Exception {
    SupportBeanClassView topView = new SupportBeanClassView(TEST_CLASS);
    List<ViewFactory> viewFactories = SupportViewSpecFactory.makeFactoryListOne(topView.getEventType());
    AgentInstanceViewFactoryChainContext context = SupportStatementContextFactory.makeAgentInstanceViewFactoryContext();

    // Check correct views created
    List<View> views = ViewServiceHelper.instantiateChain(topView, viewFactories, context);

    assertEquals(3, views.size());
    assertEquals(LengthWindowView.class, views.get(0).getClass());
    assertEquals(UnivariateStatisticsView.class, views.get(1).getClass());
    assertEquals(LastElementView.class, views.get(2).getClass());

    // Check that the context is set
    viewFactories = SupportViewSpecFactory.makeFactoryListFive(topView.getEventType());
    views = ViewServiceHelper.instantiateChain(topView, viewFactories, context);
