Class AutoCloseableReadWriteLock

java.lang.Object

java.util.concurrent.locks.ReentrantReadWriteLock

org.metricshub.wmi.AutoCloseableReadWriteLock

All Implemented Interfaces:

Serializable, ReadWriteLock

public class AutoCloseableReadWriteLock
extends ReentrantReadWriteLock

Auto-closeable version of ReentrantReadWriteLock

Example:

 AutoCloseableReadWriteLock rwLock = new AutoCloseableReadWriteLock();

 try (AutoCloseableReadWriteLock.AutoCloseableReadLock readLock = rwLock.read()) {
        // Do things that do not require exclusive access
 }
 // Read lock (non-exclusive) is unlocked automatically here

 try (AutoCloseableReadWriteLock.AutoCloseableWriteLock writeLock = rwLock.write()) {
        // Do things that require exclusive access
 }
 // Lock is unlocked automatically here
