Examples with Promise org.apache.cassandra.utils.concurrent.Promise used on opensource projects

Example 1 with Promise

use of org.apache.cassandra.utils.concurrent.Promise in project cassandra by apache.

the class AsyncChannelPromiseTest method testTimeout.

@Test
public void testTimeout() {
    final AtomicInteger initialListeners = new AtomicInteger();
    List<Supplier<Promise<Void>>> suppliers = suppliers(initialListeners, true);
    for (Supplier<Promise<Void>> supplier : suppliers) testOneTimeout(supplier.get());
    Assert.assertEquals(0, initialListeners.get());
}

Example 2 with Promise

use of org.apache.cassandra.utils.concurrent.Promise in project cassandra by apache.

the class AsyncChannelPromiseTest method testFailure.

@Test
public void testFailure() {
    final AtomicInteger initialListeners = new AtomicInteger();
    List<Supplier<Promise<Void>>> suppliers = suppliers(initialListeners, true);
    for (boolean tryOrSet : new boolean[] { false, true }) for (Throwable v : new Throwable[] { null, new NullPointerException() }) for (Supplier<Promise<Void>> supplier : suppliers) testOneFailure(supplier.get(), tryOrSet, v, null);
    Assert.assertEquals(2 * 2 * 2, initialListeners.get());
}
