Method Detail

awaitUninterruptibly

public WaitQueue.Signal awaitUninterruptibly()

Description copied from class: Awaitable.AbstractAwaitable

Awaitable.awaitUninterruptibly()

Specified by:

awaitUninterruptibly in interface Awaitable

Overrides:

awaitUninterruptibly in class Awaitable.AbstractAwaitable

await

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

Description copied from interface: WaitQueue.Signal

Await indefinitely, throwing any interrupt. No spurious wakeups. Important: the signal can be cancelled if the thread executing await() is interrupted

Specified by:

await in interface Awaitable

Specified by:

await in interface WaitQueue.Signal

Throws:

java.lang.InterruptedException - if interrupted

awaitUntilUninterruptibly

public boolean awaitUntilUninterruptibly(long nanoTimeDeadline)

Description copied from class: Awaitable.AbstractAwaitable

Awaitable.awaitUntilUninterruptibly(long)

Specified by:

awaitUntilUninterruptibly in interface Awaitable

Overrides:

awaitUntilUninterruptibly in class Awaitable.AbstractAwaitable

Returns:

true if we were signalled, false if the deadline elapsed

awaitUntil

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

Description copied from interface: WaitQueue.Signal

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

Specified by:

awaitUntil in interface Awaitable

Specified by:

awaitUntil in interface WaitQueue.Signal

Returns:

true if we were signalled, false if the deadline elapsed Important: the signal can be cancelled if the thread executing await() is interrupted

Throws:

java.lang.InterruptedException - if interrupted
