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

Usage

From source file:org.kurento.tutorial.helloworld.HelloWorldController.java

@RequestMapping(value = "/helloworld", method = RequestMethod.POST)
private String processRequest(@RequestBody String sdpOffer) {

    final CountDownLatch eventReceived = new CountDownLatch(1);
    // Media Logic
    MediaPipeline pipeline = kurento.createMediaPipeline();
