public interface RLock extends Lock, RExpirable, RLockAsync
Lock
Implements reentrant lock.
Use getHoldCount() to get a holds count.| Modifier and Type | Method and Description |
|---|---|
boolean |
forceUnlock()
Unlocks lock independently of state
|
int |
getHoldCount()
Number of holds on this lock by the current thread
|
boolean |
isHeldByCurrentThread()
Checks if this lock is held by the current thread
|
boolean |
isHeldByThread(long threadId)
Checks if this lock is held by the current thread
|
boolean |
isLocked()
Checks if this lock locked by any thread
|
void |
lock(long leaseTime,
TimeUnit unit)
Acquires the lock.
|
void |
lockInterruptibly(long leaseTime,
TimeUnit unit)
Acquires the lock.
|
boolean |
tryLock(long waitTime,
long leaseTime,
TimeUnit unit)
Returns
true as soon as the lock is acquired. |

If the lock is not available then the current thread becomes
disabled for thread scheduling purposes and lies dormant until the
lock has been acquired.
If the lock is acquired, it is held until unlock is invoked,
or until leaseTime have passed
since the lock was granted - whichever comes first.
leaseTime - the maximum time to hold the lock after granting it,
before automatically releasing it if it hasn't already been released by invoking unlock.

true as soon as the lock is acquired.
If the lock is currently held by another thread in this or any
other process in the distributed system this method keeps trying
to acquire the lock for up to waitTime before
giving up and returning false. If the lock is acquired,
it is held until unlock is invoked, or until leaseTime

If the lock is acquired, it is held until unlock is invoked,
