edu.emory.mathcs.backport.java.util.concurrent.locks.Lock.lockInterruptibly()
Acquires the lock unless the current thread is {@link Thread#interrupt interrupted}.
Acquires the lock if it is available and returns immediately.
If the lock is not available then the current thread becomes disabled for thread scheduling purposes and lies dormant until one of two things happens:
- The lock is acquired by the current thread; or
- Some other thread {@link Thread#interrupt interrupts} the currentthread, and interruption of lock acquisition is supported.
If the current thread:
- has its interrupted status set on entry to this method; or
- is {@link Thread#interrupt interrupted} while acquiringthe lock, and interruption of lock acquisition is supported,
then {@link InterruptedException} is thrown and the current thread'sinterrupted status is cleared.
Implementation Considerations
The ability to interrupt a lock acquisition in some implementations may not be possible, and if possible may be an expensive operation. The programmer should be aware that this may be the case. An implementation should document when this is the case.
An implementation can favor responding to an interrupt over normal method return.
A Lock implementation may be able to detect erroneous use of the lock, such as an invocation that would cause deadlock, and may throw an (unchecked) exception in such circumstances. The circumstances and the exception type must be documented by that Lock implementation. @throws InterruptedException if the current thread is interruptedwhile acquiring the lock (and interruption of lock acquisition is supported). @see Thread#interrupt
