  java.lang.management.LockInfo
Direct Known Subclasses:
MonitorInfo
public class LockInfo
extends Object
Information about a lock. A lock can be a built-in object monitor, an ownable synchronizer, or the Condition object associated with synchronizers.

An ownable synchronizer is a synchronizer that may be exclusively owned by a thread and uses AbstractOwnableSynchronizer (or its subclass) to implement its synchronization property. ReentrantLock and ReentrantReadWriteLock are two examples of ownable synchronizers provided by the platform.

MXBean Mapping

LockInfo is mapped to a CompositeData as specified in the type mapping rules of MXBeans.
