 public class LockInfo extends Object Information about a lock. A lock can be a built-in object monitor, an ownable synchronizer, or theConditionobject 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.ReentrantLockand the write-lock (but not the read-lock) ofReentrantReadWriteLockare two examples of ownable synchronizers provided by the platform.MXBean MappingLockInfois mapped to aCompositeDataas specified in thefrommethod.- Since:

Method Detail- 
getClassNamepublic String getClassName() Returns the fully qualified name of the class of the lock object.- Returns:
- the fully qualified name of the class of the lock object.
 
 - 
getIdentityHashCodepublic int getIdentityHashCode() Returns the identity hash code of the lock object returned from theSystem.identityHashCode(java.lang.Object)method.- Returns:
- the identity hash code of the lock object.

frompublic static LockInfo from(CompositeData cd) Returns aLockInfoobject represented by the givenCompositeData. The givenCompositeDatamust contain the following attributes:Attribute Name Type className java.lang.StringidentityHashCode java.lang.Integer- Parameters:
- cd-- CompositeDatarepresenting a- LockInfo
- Returns:
- a LockInfoobject represented bycdifcdis notnull;nullotherwise.
- Throws:
- IllegalArgumentException- if- cddoes not represent a- LockInfowith the attributes described above.

toStringpublic String toString() 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:
 wherelock.getClass().getName() + '@' + Integer.toHexString(System.identityHashCode(lock)) lockis the lock object.
