Method Detail

equals

public boolean equals(Object aOther)

getClass

public final Class<?> getClass()

Returns null. It's here to satisfy javac.

hashCode

public int hashCode()

notify

public final void notify()

Wake up one thread blocked on a wait(). Must be synchronized on this object otherwise an IllegalMonitorStateException will be thrown.

If multiple threads are waiting, higher priority threads will be woken in preference, otherwise the thread that gets woken is essentially random.

notifyAll

public final void notifyAll()

Wake up all threads blocked on a wait(). Must be synchronized on this object otherwise an IllegalMonitorStateException will be thrown.

toString

public String toString()

wait

public final void wait()
                throws InterruptedException

This is the same as calling wait(0). TODO make this a Java method that calls wait(0) since native methods are expensive?

Throws:

InterruptedException

wait

public final void wait(long timeout)
                throws InterruptedException

Wait until notified. Must be synchronized on this object otherwise an IllegalMonitorStateException will be thrown. The wait can terminate if one of the following things occurs:

1. notify() or notifyAll() is called.
2. The calling thread is interrupted.
3. The timeout expires.

Parameters:

timeout - maximum time in milliseconds to wait. Zero means forever.

Throws:

InterruptedException

wait

public final void wait(long timeout,
                       int nanos)
                throws InterruptedException

Throws:

InterruptedException
