Example usage for java.util.concurrent CountDownLatch await

Introduction

In this page you can find the example usage for java.util.concurrent CountDownLatch await.

Prototype

public boolean await(long timeout, TimeUnit unit) throws InterruptedException 

Source Link

Document

Causes the current thread to wait until the latch has counted down to zero, unless the thread is Thread#interrupt interrupted , or the specified waiting time elapses.

Usage

From source file:com.amazonaws.eclipse.core.accounts.profiles.SdkCredentialsFileContentMonitorTest.java

@Test
public void testFileChangedCallback() throws InterruptedException {

    final CountDownLatch latch = new CountDownLatch(1);

    SdkCredentialsFileContentMonitor monitor = new SdkCredentialsFileContentMonitor(targetFile,
            MONITOR_POLLING_INTERVAL_MILLIS, new FileAlterationListenerAdaptor() {

                @Override// w w  w .j  av a2s .  c o m
                public void onFileChange(final File changedFile) {
                    latch.countDown();
                }
            });
    monitor.setDebugMode(true);
    monitor.start();

    touch(targetFile);

    long waitTime = MONITOR_POLLING_INTERVAL_MILLIS * 2;
    Assert.assertTrue("File monitor callback not invoked after waiting for " + waitTime + " ms.",
            latch.await(waitTime, TimeUnit.MILLISECONDS));
