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
