public final Class FakeTimeLimiter

Implements com.google.common.util.concurrent.TimeLimiter.callUninterruptiblyWithTimeout.

Doc from com.google.common.util.concurrent.TimeLimiter.callUninterruptiblyWithTimeout.

Invokes a specified Callable, timing out after the specified time limit. If the target method call finishes before the limit is reached, the return value or a wrapped exception is propagated. If, on the other hand, the time limit is reached, we attempt to abort the call to the target, and throw a TimeoutException to the caller.

The difference with callWithTimeout(Callable, long, TimeUnit) is that this method will ignore interrupts on the current thread.

Parameters

callable:Callable<T>

the Callable to execute

timeoutDuration:long

with timeoutUnit, the maximum length of time to wait

timeoutUnit:TimeUnit

with timeoutDuration, the maximum length of time to wait

Returns:T

the result returned by the Callable

Annotations

@CanIgnoreReturnValue

@Override

@ParametricNullness

Exceptions

ExecutionException:

if callable throws a checked exception

Implements com.google.common.util.concurrent.TimeLimiter.newProxy.

Doc from com.google.common.util.concurrent.TimeLimiter.newProxy.

Returns an instance of interfaceType that delegates all method calls to the target object, enforcing the specified time limit on each call. This time-limited delegation is also performed for calls to Object#equals, Object#hashCode, and Object#toString.

If the target method call finishes before the limit is reached, the return value or exception is propagated to the caller exactly as-is. If, on the other hand, the time limit is reached, the proxy will attempt to abort the call to the target, and will throw an UncheckedTimeoutException to the caller.

It is important to note that the primary purpose of the proxy object is to return control to the caller when the timeout elapses; aborting the target method call is of secondary concern. The particular nature and strength of the guarantees made by the proxy is implementation-dependent. However, it is important that each of the methods on the target object behaves appropriately when its thread is interrupted.

For example, to return the value of target.someMethod(), but substitute DEFAULT_VALUE if this method call takes over 50 ms, you can use this code:

  TimeLimiter limiter = . . .;
  TargetType proxy = limiter.newProxy(
      target, TargetType.class, 50, TimeUnit.MILLISECONDS);
  try {
    return proxy.someMethod();
  } catch (UncheckedTimeoutException e) {
    return DEFAULT_VALUE;
  }

Parameters

target:T

the object to proxy

interfaceType:Class<T>

the interface you wish the returned proxy to implement

timeoutDuration:long

with timeoutUnit, the maximum length of time that callers are willing to wait on each method call to the proxy

timeoutUnit:TimeUnit

with timeoutDuration, the maximum length of time that callers are willing to wait on each method call to the proxy

Returns:T

a time-limiting proxy

Implements com.google.common.util.concurrent.TimeLimiter.runUninterruptiblyWithTimeout.

Doc from com.google.common.util.concurrent.TimeLimiter.runUninterruptiblyWithTimeout.

Invokes a specified Runnable, timing out after the specified time limit. If the target method run finishes before the limit is reached, this method returns or a wrapped exception is propagated. If, on the other hand, the time limit is reached, we attempt to abort the run, and throw a TimeoutException to the caller.

The difference with runWithTimeout(Runnable, long, TimeUnit) is that this method will ignore interrupts on the current thread.

Parameters

runnable:Runnable

the Runnable to execute

timeoutDuration:long

with timeoutUnit, the maximum length of time to wait

timeoutUnit:TimeUnit

with timeoutDuration, the maximum length of time to wait
