Class LockInfo
java.lang.Object
java.lang.management.LockInfo
- Direct Known Subclasses:
- MonitorInfo
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 the write-lock (but not
 the read-lock) of ReentrantReadWriteLock are
 two examples of ownable synchronizers provided by the platform.

- 
toStringReturns a string representation of a lock. The returned string representation consists of the name of the class of the lock object, the at-sign character `@', and the unsigned hexadecimal representation of the identity hash code of the object. This method returns a string equals to the value of:
 wherelock.getClass().getName() + '@' + Integer.toHexString(System.identityHashCode(lock)) lockis the lock object.
