The maximum number of elements that a queue can hold.
The maximum number of elements that a queue can hold.
that unbounded queues can still implement this interface with capacity =
MAX_INT.
the number of elements that have ever been taken from the queue.
if you know how much time the queue is alive, you can calculate the rate at which elements are being dequeued.
the number of elements that have ever been added to the queue.
if you know how much time the queue is alive, you can calculate the rate at which elements are being enqueued.
,
that Long is used here, since Int will be overflowed really quickly
for busy queues.
A non-blocking enqueue.
A non-blocking enqueue.
whether the enqueue was successful or not.
A non-blocking enqueue of multiple elements.
A non-blocking enqueue of multiple elements.
A non-blocking dequeue.
A non-blocking dequeue.
either an element from the queue, or the default param.
that if there's no meaningful default for your type, you can always use
poll(null). Not the best, but reasonable price to pay for lower heap
churn from not using Option here.
A non-blocking dequeue of multiple elements.
A non-blocking dequeue of multiple elements.
the current number of elements inside the queue.
that this method can be non-atomic and return the approximate number in a concurrent setting.
