## java.lang.management
Class LockInfo

    java.lang.Object
      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.

Since:
  1.6
See Also:
  `AbstractOwnableSynchronizer`, `Condition`

Constructor Summary
`LockInfo(String className, int identityHashCode)` Constructs a `LockInfo` object.

Method Summary
`String` | `getClassName()` Returns the fully qualified name of the class of the lock object.
`int` | `getIdentityHashCode()` Returns the identity hash code of the lock object returned from the `System.identityHashCode(java.lang.Object)` method.
`String` | `toString()` Returns a string representation of a lock.

Constructor Detail

### LockInfo

    @ConstructorProperties(value={"className","identityHashCode"})
    public LockInfo(String className,
                                               int identityHashCode)

  Constructs a `LockInfo` object.

  Parameters:
    `className` - the fully qualified name of the class of the lock object.
    `identityHashCode` - the `identity hash code` of the lock object.

Method Detail

### getClassName

    public 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.

### getIdentityHashCode

    public int getIdentityHashCode()

  Returns the identity hash code of the lock object returned from the `System.identityHashCode(java.lang.Object)` method.

  Returns:
    the identity hash code of the lock object.

### toString

    public 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:

  >      lock.getClass().getName() + '@' + Integer.toHexString(System.identityHashCode(lock))

  where `lock` is the lock object.

  Overrides:
    `toString` in class `Object`
  Returns:
    the string representation of a lock.
