All known Subclasses: java.util.concurrent.locks.AbstractQueuedSynchronizer, java.util.concurrent.locks.AbstractQueuedLongSynchronizer,
| AbstractOwnableSynchronizer | | abstract public class AbstractOwnableSynchronizer implements java.io.Serializable(Code) | | 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.
