Method Detail

await

public WaitQueue.Signal await()
                       throws java.lang.InterruptedException

Description copied from interface: Awaitable

Await indefinitely, throwing any interrupt. No spurious wakeups.

Specified by:

await in interface Awaitable

Throws:

java.lang.InterruptedException - if interrupted

awaitUntil

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

Description copied from interface: Awaitable

Await until the deadline (in nanoTime), throwing any interrupt. No spurious wakeups.

Specified by:

awaitUntil in interface Awaitable

Returns:

true if we were signalled, false if the deadline elapsed
