Interface ReentrantLock

All Known Implementing Classes:

ReentrantReadWriteLock.AbstractLock, ReentrantReadWriteLock.ReadLock, ReentrantReadWriteLock.WriteLock

interface ReentrantLock

Similar to java.util.concurrent.locks.Lock, but simplified and adapted to the particular needs of TrueZIP. The subset of methods common to both this interface and its cousin in JSE 1.5 is identical in functionality. However, some other methods have been added here in order to suit the particular needs of TrueZIP (see ArchiveController).

Since:

TrueZIP 6.2

Method Summary

boolean	isLocked() Returns true if and only if the current thread has acquired this lock.
void	lock() Acquires this lock by the current thread, eventually blocking.
int	lockCount() Returns the number of times the current thread has successfully acquired this lock.
void	lockInterruptibly() Acquires this lock by the current thread unless it is interrupted, eventually blocking.
boolean	tryLock() Acquires this lock if and only if it is available at the time of invocation by the current thread and returns true.
void	unlock() Releases this lock.
