方法详细资料

instance

public static Schedule instance()

Get the singleton instance.

返回:

singleton instance

close

public void close()

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

createInvalidHandle

public static EventHandle createInvalidHandle()

Used for CAS. For example:

     static class DisposableImpl implements JDisposable {

         // Create a handle placeholder representing invalid handle.
         private static final EventHandle INVALID = Schedule.createInvalidHandle();
         private volatile EventHandle handle;
         private static final AtomicReferenceFieldUpdater HANDLE
                 = AtomicReferenceFieldUpdater.newUpdater(DisposableImpl.class, EventHandle.class, "handle");

         void updateHandle(EventHandle newHandle) {
             while (true) {
                 EventHandle handle = this.handle;
                 if (handle == INVALID || HANDLE.weakCompareAndSet(this, handle, newHandle)) {
                     return;
                 }
             }
         }

         public void dispose() {
             while (true) {
                 EventHandle handle = this.handle;
                 if (handle == INVALID) {
                     return;
                 }
                 if (HANDLE.weakCompareAndSet(this, handle, INVALID)) {
                     handle.remove();
                     return;
                 }
             }
         }

         public boolean isDisposed() {
             return handle == INVALID;
         }
     }
 

返回:

a invalid handle.

addEvent

public EventHandle addEvent(long time,
                            TimeUnit unit,
                            Runnable callback)

schedule the callback
