LockInfo (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

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 {@link Condition Condition} object associated with synchronizers.

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

MXBean Mapping

LockInfo is mapped to a {@link CompositeData CompositeData} as specified in the type mapping rules of {@linkplain javax.management.MXBean MXBeans}.

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 java.lang.System.identityHashCode method.
`String`	`toString()` Returns a string representation of a lock.

Constructor Detail

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 {@link System#identityHashCode 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 {@link System#identityHashCode} 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.
