Class FakeTimeLimiter
java.lang.Object
  com.google.common.util.concurrent.FakeTimeLimiter


All Implemented Interfaces: 
TimeLimiter



@Beta
public final class FakeTimeLimiterextends Object
implements TimeLimiter




A TimeLimiter implementation which actually does not attempt to limit time
 at all.  This may be desirable to use in some unit tests.  More importantly,
 attempting to debug a call which is time-limited would be extremely annoying,
 so this gives you a time-limiter you can easily swap in for your real
 time-limiter while you're debugging.

Method Detail




newProxy
public <T> T newProxy(T target,
                      Class<T> interfaceType,
                      long timeoutDuration,
                      TimeUnit timeoutUnit)

Description copied from interface: TimeLimiter
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(java.lang.Object), 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.


Specified by:
newProxy in interface TimeLimiter


Parameters:
target - the object to proxy
interfaceType - the interface you wish the returned proxy to
     implement
timeoutDuration - with timeoutUnit, the maximum length of time that
     callers are willing to wait on each method call to the proxy
timeoutUnit - with timeoutDuration, the maximum length of time that
     callers are willing to wait on each method call to the proxy
Returns:
a time-limiting proxy





callWithTimeout
public <T> T callWithTimeout(Callable<T> callable,
                             long timeoutDuration,
                             TimeUnit timeoutUnit,
                             boolean amInterruptible)
                  throws Exception

Description copied from interface: TimeLimiter
Invokes a specified Callable, timing out after the specified time limit.
 If the target method call finished 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, we attempt to abort the call to the
 target, and throw an UncheckedTimeoutException to the caller.
 
 Warning: The future of this method is in doubt.  It may be nuked, or
 changed significantly.


Specified by:
callWithTimeout in interface TimeLimiter


Parameters:
callable - the Callable to execute
timeoutDuration - with timeoutUnit, the maximum length of time to wait
timeoutUnit - with timeoutDuration, the maximum length of time to wait
amInterruptible - whether to respond to thread interruption by aborting
     the operation and throwing InterruptedException; if false, the
     operation is allowed to complete or time out, and the current thread's
     interrupt status is re-asserted.
Returns:
the result returned by the Callable
Throws:
InterruptedException - if interruptible is true and our
     thread is interrupted during execution
UncheckedTimeoutException - if the time limit is reached
Exception
