java.lang.Object
   java.lang.management.LockInfo

All known Subclasses:   java.lang.management.MonitorInfo,
LockInfo
public class LockInfo (Code)
Information about a lock. A lock can be a built-in object monitor, an ownable synchronizer, or the Condition Condition object associated with synchronizers.

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

MXBean Mapping

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

Constructor Summary
public  LockInfo(String className, int identityHashCode)
     Constructs a LockInfo object.
 LockInfo(Object lock)
    

Method Summary
public  StringgetClassName()
     Returns the fully qualified name of the class of the lock object.

Constructor Detail
LockInfo
public LockInfo(String className, int identityHashCode)(Code)
Constructs a LockInfo object.
Parameters:
  className - the fully qualified name of the class of the lock object.
Parameters:
  identityHashCode - the System.identityHashCode identity hash code of the lock object.


LockInfo
LockInfo(Object lock)(Code)
package-private constructors



Method Detail
getClassName
public String getClassName()(Code)
Returns the fully qualified name of the class of the lock object. the fully qualified name of the class of the lock object.


getIdentityHashCode
public int getIdentityHashCode()(Code)
Returns the identity hash code of the lock object returned from the System.identityHashCode method. the identity hash code of the lock object.


toString
public String toString()(Code)
Returns 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: 
 lock.getClass().getName() + '@' + Integer.toHexString(System.identityHashCode(lock))
where lock is the lock object. the string representation of a lock.
