Examples of java.lang.management.LockInfo

java.lang.management.LockInfo
Information about a lock. A lock can be a built-in object monitor, an ownable synchronizer, or the {@link Condition Condition}object associated with synchronizers.
An ownable synchronizer is a synchronizer that may be exclusively owned by a thread and uses {@link AbstractOwnableSynchronizer AbstractOwnableSynchronizer} (or its subclass) to implement its synchronization property. {@link ReentrantLock ReentrantLock} and{@link ReentrantReadWriteLock ReentrantReadWriteLock} aretwo examples of ownable synchronizers provided by the platform.
MXBean Mapping
LockInfo is mapped to a {@link CompositeData CompositeData}as specified in the type mapping rules of {@linkplain javax.management.MXBean MXBeans}. @see java.util.concurrent.locks.AbstractOwnableSynchronizer @see java.util.concurrent.locks.Condition @author Mandy Chung @version 1.6, 02/27/06 @since 1.6
