:relfileprefix: ../../../
:mrdocs:

Disable dequeueing from this queue. All subsequent invocations of `popFront` or `tryPopFront` will fail immediately. If the single consumer is blocked in `popFront`, the invocation of `popFront` will fail immediately. Any blocked invocations of `waitUntilEmpty` will fail immediately. If the queue is already dequeue disabled, this method has no effect.
