Package Summary Overview Summary

class:LockInfo [NONE]

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 the write-lock (but not the read-lock) of ReentrantReadWriteLock are two examples of ownable synchronizers provided by the platform.

MXBean Mapping
LockInfo is mapped to a CompositeData as specified in the from method.

constructor:<init>(java.lang.String,int) [NONE]

LockInfo
```
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:getClassName() [NONE]

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.

method:getIdentityHashCode() [NONE]

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.

method:from(javax.management.openmbean.CompositeData) [NONE]

from
```
public static LockInfo from(CompositeData cd)
```
Returns a LockInfo object represented by the given CompositeData. The given CompositeData must contain the following attributes:
The attributes and the types the given CompositeData contains

Attribute Name Type

className java.lang.String

identityHashCode java.lang.Integer

Parameters:

cd - CompositeData representing a LockInfo

Returns:

a LockInfo object represented by cd if cd is not null; null otherwise.

Throws:

IllegalArgumentException - if cd does not represent a LockInfo with the attributes described above.

Since:

1.8

method:toString() [NONE]

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.
