Types

type DelayQueue

type DelayQueue struct {
	C chan interface{}
	// contains filtered or unexported fields
}

DelayQueue is an unbounded blocking queue of *Delayed* elements, in which an element can only be taken when its delay has expired. The head of the queue is the *Delayed* element whose delay expired furthest in the past.

func New

func New(size int) *DelayQueue

New creates an instance of delayQueue with the specified size.

func (*DelayQueue) Offer

func (dq *DelayQueue) Offer(elem interface{}, expiration int64)

Offer inserts the element into the current queue.

func (*DelayQueue) Poll

func (dq *DelayQueue) Poll(exitC chan struct{}, nowF func() int64)

Poll starts an infinite loop, in which it continually waits for an element to expire and then send the expired element to the channel C.
