Class Uninterruptibles

java.lang.Object

com.google.common.util.concurrent.Uninterruptibles

@Beta
public final class Uninterruptibles
extends Object

Utilities for treating interruptible operations as uninterruptible. In all cases, if a thread is interrupted during such a call, the call continues to block until the result is available or the timeout elapses, and only then re-interrupts the thread.

Method Detail

awaitUninterruptibly

public static void awaitUninterruptibly(CountDownLatch latch)

Invokes latch.await() uninterruptibly.

awaitUninterruptibly

public static boolean awaitUninterruptibly(CountDownLatch latch,
                           long timeout,
                           TimeUnit unit)

Invokes latch.await(timeout, unit) uninterruptibly.

joinUninterruptibly

public static void joinUninterruptibly(Thread toJoin)

Invokes toJoin.join() uninterruptibly.

getUninterruptibly

public static <V> V getUninterruptibly(Future<V> future)
                            throws ExecutionException

Invokes future.get() uninterruptibly. To get uninterruptibility and remove checked exceptions, see Futures.getUnchecked(java.util.concurrent.Future<V>).

If instead, you wish to treat InterruptedException uniformly with other exceptions, see Futures.get or Futures.makeChecked(com.google.common.util.concurrent.ListenableFuture<V>, com.google.common.base.Function<java.lang.Exception, X>).

Throws:

ExecutionException - if the computation threw an exception

CancellationException - if the computation was cancelled

getUninterruptibly

public static <V> V getUninterruptibly(Future<V> future,
                       long timeout,
                       TimeUnit unit)
                            throws ExecutionException,
                                   TimeoutException

Invokes future.get(timeout, unit) uninterruptibly.

If instead, you wish to treat InterruptedException uniformly with other exceptions, see Futures.get or Futures.makeChecked(com.google.common.util.concurrent.ListenableFuture<V>, com.google.common.base.Function<java.lang.Exception, X>).

Throws:

ExecutionException - if the computation threw an exception

CancellationException - if the computation was cancelled

TimeoutException - if the wait timed out

joinUninterruptibly

public static void joinUninterruptibly(Thread toJoin,
                       long timeout,
                       TimeUnit unit)

Invokes unit.timedJoin(toJoin, timeout) uninterruptibly.

takeUninterruptibly

public static <E> E takeUninterruptibly(BlockingQueue<E> queue)

Invokes queue.take() uninterruptibly.

putUninterruptibly

public static <E> void putUninterruptibly(BlockingQueue<E> queue,
                          E element)

Invokes queue.put(element) uninterruptibly.

Throws:

ClassCastException - if the class of the specified element prevents it from being added to the given queue

IllegalArgumentException - if some property of the specified element prevents it from being added to the given queue

sleepUninterruptibly

public static void sleepUninterruptibly(long sleepFor,
                        TimeUnit unit)

Invokes unit.sleep(sleepFor) uninterruptibly.
