Abstract Value Members
- abstract val capacity: Int
The maximum number of elements that a queue can hold.
The maximum number of elements that a queue can hold.
- Definition Classes
- MutableConcurrentQueue
- Note
that unbounded queues can still implement this interface with
capacity = MAX_INT.
- abstract def dequeuedCount(): Long
- returns
the number of elements that have ever been taken from the queue.
- Definition Classes
- MutableConcurrentQueue
- Note
if you know how much time the queue is alive, you can calculate the rate at which elements are being dequeued.
- abstract def enqueuedCount(): Long
- returns
the number of elements that have ever been added to the queue.
- Definition Classes
- MutableConcurrentQueue
- Note
that
,Longis used here, sinceIntwill be overflowed really quickly for busy queues.if you know how much time the queue is alive, you can calculate the rate at which elements are being enqueued.
- abstract def isEmpty(): Boolean
- Definition Classes
- MutableConcurrentQueue
- abstract def isFull(): Boolean
- Definition Classes
- MutableConcurrentQueue
- abstract def offer(a: A): Boolean
A non-blocking enqueue.
A non-blocking enqueue.
- returns
whether the enqueue was successful or not.
- Definition Classes
- MutableConcurrentQueue
- abstract def poll(default: A): A
A non-blocking dequeue.
A non-blocking dequeue.
- returns
either an element from the queue, or the
defaultparam.
- Definition Classes
- MutableConcurrentQueue
- Note
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 usingOptionhere.
- abstract def size(): Int
- returns
the current number of elements inside the queue.
- Definition Classes
- MutableConcurrentQueue
- Note
that this method can be non-atomic and return the approximate number in a concurrent setting.
