AbstractOwnableSynchronizer

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.

Protected Methods
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.
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.
