AbstractOwnableSynchronizer

public abstract class AbstractOwnableSynchronizer
extends Object implements Serializable

java.lang.Object
   ↳ java.util.concurrent.locks.AbstractOwnableSynchronizer
AbstractQueuedLongSynchronizer A version of AbstractQueuedSynchronizer in which synchronization state is maintained as a long
AbstractQueuedSynchronizer Provides a framework for implementing blocking locks and related synchronizers (semaphores, events, etc) that rely on first-in-first-out (FIFO) wait queues. 


A synchronizer that may be exclusively owned by a thread. This class provides a basis for creating locks and related synchronizers that may entail a notion of ownership. The AbstractOwnableSynchronizer class itself does not manage or use this information. However, subclasses and tools may use appropriately maintained values to help control and monitor access and provide diagnostics.

Summary

Protected constructors

AbstractOwnableSynchronizer()

Empty constructor for use by subclasses.

Protected methods

final Thread getExclusiveOwnerThread()

Returns the thread last set by setExclusiveOwnerThread, or null if never set.

final void setExclusiveOwnerThread(Thread thread)

Sets the thread that currently owns exclusive access.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Protected constructors

AbstractOwnableSynchronizer

Added in API level 5
protected AbstractOwnableSynchronizer ()

Empty constructor for use by subclasses.

Protected methods

getExclusiveOwnerThread

Added in API level 5
protected final Thread getExclusiveOwnerThread ()

Returns the thread last set by setExclusiveOwnerThread, or null if never set. This method does not otherwise impose any synchronization or volatile field accesses.

Returns
Thread the owner thread

setExclusiveOwnerThread

Added in API level 5
protected final void setExclusiveOwnerThread (Thread thread)

Sets the thread that currently owns exclusive access. A null argument indicates that no thread owns access. This method does not otherwise impose any synchronization or volatile field accesses.

Parameters
thread Thread: the owner thread
