Examples with FutureHelper org.webpieces.util.futures.FutureHelper used on opensource projects

Example 1 with FutureHelper

use of org.webpieces.util.futures.FutureHelper in project webpieces by deanhiller.

the class TestFilters method testFilters.

/**
 * Filter demonstration.  Could make more advanced but this works great and I prefer KISS so
 * others that read it can understand it easier as it is already more complicated than I wish.
 * @throws ExecutionException
 * @throws InterruptedException
 */
@Test
public void testFilters() throws InterruptedException, ExecutionException {
    Filter.setFutureUtil(new FutureHelper());
    MyFilter filterMiddle = new MyFilter("middle");
    MyFilter filterTop = new MyFilter("top");
    Service<Integer, String> service2 = filterTop.chain(filterMiddle).chain(new SomeService());
    Service<Integer, String> x3 = filterMiddle.chain(filterTop).chain(new SomeService());
    XFuture<String> future = service2.invoke(5);
    String result = future.get();
    Assert.assertEquals("top", result);
    XFuture<String> future2 = x3.invoke(2);
    String result2 = future2.get();
    Assert.assertEquals("middle", result2);
