List of attempt() Examples

Examples of attempt()

EDU.oswego.cs.dl.util.concurrent.CountDown.attempt()
EDU.oswego.cs.dl.util.concurrent.Latch.attempt()
EDU.oswego.cs.dl.util.concurrent.Semaphore.attempt()
Wait at most msecs millisconds for a permit.
EDU.oswego.cs.dl.util.concurrent.Sync.attempt()
Wait at most msecs to pass; report whether passed.
The method has best-effort semantics: The msecs bound cannot be guaranteed to be a precise upper bound on wait time in Java. Implementations generally can only attempt to return as soon as possible after the specified bound. Also, timers in Java do not stop during garbage collection, so timeouts can occur just because a GC intervened. So, msecs arguments should be used in a coarse-grained manner. Further, implementations cannot always guarantee that this method will return at all without blocking indefinitely when used in unintended ways. For example, deadlocks may be encountered when called in an unintended context.
@param msecs the number of milleseconds to wait.An argument less than or equal to zero means not to wait at all. However, this may still require access to a synchronization lock, which can impose unbounded delay if there is a lot of contention among threads. @return true if acquired
com.cloudera.util.RetryHarness.attempt()
Calls doTry on a Retryable until either it succeeds or the backoff policy fails.
net.sf.ehcache.concurrent.Mutex.attempt()
@param msecs the number of milleseconds to wait.An argument less than or equal to zero means not to wait at all. However, this may still require access to a synchronization lock, which can impose unbounded delay if there is a lot of contention among threads. @return true if acquired @see Sync#attempt(long)
net.sf.ehcache.constructs.concurrent.Mutex.attempt()
@param msecs the number of milleseconds to wait.An argument less than or equal to zero means not to wait at all. However, this may still require access to a synchronization lock, which can impose unbounded delay if there is a lot of contention among threads. @return true if acquired @see Sync#attempt(long)
org.exist.storage.lock.Lock.attempt()
Attempt to acquire a lock for read or write. This method will fail immediately if the lock cannot be acquired. @param mode
org.jboss.ejb.plugins.lock.NonReentrantLock.attempt()
org.vmmagic.unboxed.Address.attempt()
Attempt an atomic store operation. This must be associated with a related call to prepare. @param old the old value. @param value the new value. @return true if the attempt was successful.
