Method Summary

Modifier and Type	Method and Description
private void	_threadTerminated()
public static void	register(TerminatingThreadLocal<?> the ThreadLocal to register tl) Register given TerminatingThreadLocal
public void	remove() Overrides jdk.internal.misc.CarrierThreadLocal.remove. Removes the current thread's value for this thread-local variable.
public void	set(T value) Overrides jdk.internal.misc.CarrierThreadLocal.set. Sets the current thread's copy of this thread-local variable to the specified value.
protected void	threadTerminated(T current thread's value of this thread-local variable (may be null but only if null value was explicitly initialized) value) Invoked by a thread when terminating and this thread-local has an associated value for the terminating thread (even if that value is null), so that any native resources maintained by the value can be released.
public static void	threadTerminated() Invokes the TerminatingThreadLocal's `threadTerminated()` method on all instances registered in current thread.
private static void	unregister(TerminatingThreadLocal<?> the ThreadLocal to unregister tl) Unregister given TerminatingThreadLocal

remove back to summary

remove	back to summary
public void remove() Overrides jdk.internal.misc.CarrierThreadLocal.remove. Doc from java.lang.ThreadLocal.remove. Removes the current thread's value for this thread-local variable. If this thread-local variable is subsequently read by the current thread, its value will be reinitialized by invoking its `initialValue` method, unless its value is set by the current thread in the interim. This may result in multiple invocations of the `initialValue` method in the current thread. Annotations @Override

public void remove()

Overrides jdk.internal.misc.CarrierThreadLocal.remove.

Doc from java.lang.ThreadLocal.remove.

Removes the current thread's value for this thread-local variable. If this thread-local variable is subsequently read by the current thread, its value will be reinitialized by invoking its initialValue method, unless its value is set by the current thread in the interim. This may result in multiple invocations of the initialValue method in the current thread.

set	back to summary
public void set(T value) Overrides jdk.internal.misc.CarrierThreadLocal.set. Doc from java.lang.ThreadLocal.set. Sets the current thread's copy of this thread-local variable to the specified value. Most subclasses will have no need to override this method, relying solely on the `initialValue` method to set the values of thread-locals. Annotations @Override

public void set(T value)

Overrides jdk.internal.misc.CarrierThreadLocal.set.

Doc from java.lang.ThreadLocal.set.

Sets the current thread's copy of this thread-local variable to the specified value. Most subclasses will have no need to override this method, relying solely on the initialValue method to set the values of thread-locals.

Annotations

@Override

threadTerminated	back to summary
protected void threadTerminated(T value) Invoked by a thread when terminating and this thread-local has an associated value for the terminating thread (even if that value is null), so that any native resources maintained by the value can be released. Parameters value:T current thread's value of this thread-local variable (may be null but only if null value was explicitly initialized)

threadTerminated

back to summary

protected void threadTerminated(T value)

Invoked by a thread when terminating and this thread-local has an associated value for the terminating thread (even if that value is null), so that any native resources maintained by the value can be released.

Parameters

value:T: current thread's value of this thread-local variable (may be null but only if null value was explicitly initialized)

threadTerminated	back to summary
public static void threadTerminated() Invokes the TerminatingThreadLocal's `threadTerminated()` method on all instances registered in current thread.
