Method Detail

await

public Awaitable await()
                throws java.lang.InterruptedException

Awaitable.await()

Throws:

java.lang.InterruptedException - if interrupted

awaitUntil

public boolean awaitUntil(long nanoTimeDeadline)
                   throws java.lang.InterruptedException

Awaitable.awaitUntil(long)

true if we were signalled, false if the deadline elapsed

Throws:

java.lang.InterruptedException - if interrupted

isSignalled

protected abstract boolean isSignalled()

Return true once signalled. Unidirectional; once true, must never again be false.

waitUntil

public static boolean waitUntil(java.lang.Object monitor,
                                long deadlineNanos)
                         throws java.lang.InterruptedException
