Class Uninterruptibles

java.lang.Object

com.google.common.util.concurrent.Uninterruptibles

@Beta
 @GwtCompatible(emulated=true)
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.

                                                                                   TimeUnit unit)

Invokes latch.await(timeout, unit) uninterruptibly.

awaitUninterruptibly

@GwtIncompatible
public static boolean awaitUninterruptibly(Condition condition,
                                                            long timeout,
                                                            TimeUnit unit)

Invokes condition.await(timeout, unit) uninterruptibly.

Since:

23.6

joinUninterruptibly

@GwtIncompatible
public static void joinUninterruptibly(Thread toJoin)

Invokes toJoin.join() uninterruptibly.

joinUninterruptibly

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

Invokes unit.timedJoin(toJoin, timeout) uninterruptibly.

getUninterruptibly

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

Invokes future.get() uninterruptibly.

Similar methods:

• To retrieve a result from a Future that is already done, use Futures.getDone.
• To treat InterruptedException uniformly with other exceptions, use Futures.getChecked.
• To get uninterruptibility and remove checked exceptions, use Futures.getUnchecked(java.util.concurrent.Future<V>).

Throws:

ExecutionException - if the computation threw an exception

CancellationException - if the computation was cancelled

getUninterruptibly

@CanIgnoreReturnValue
 @GwtIncompatible
public static <V> V getUninterruptibly(Future<V> future,
                                                                               long timeout,

Invokes future.get(timeout, unit) uninterruptibly.

Similar methods:

• To retrieve a result from a Future that is already done, use Futures.getDone.
• To treat InterruptedException uniformly with other exceptions, use Futures.getChecked.
• To get uninterruptibility and remove checked exceptions, use Futures.getUnchecked(java.util.concurrent.Future<V>).

Throws:

ExecutionException - if the computation threw an exception

CancellationException - if the computation was cancelled

TimeoutException - if the wait timed out

Invokes queue.put(element) uninterruptibly.

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
