A type synonym for the ordinary FIFO queue also known as the FCFS (First Come - First Serviced) queue.

A type synonym for the ordinary LIFO queue also known as the LCFS (Last Come - First Serviced) queue.

A type synonym for the SIRO (Serviced in Random Order) queue.

A type synonym for the queue with static priorities applied when storing the elements in the queue.

Represents an infinite queue using the specified strategies for internal storing (in memory), sm, and dequeueing (output), so, where a denotes the type of items stored in the queue.

The strategy applied when storing (in memory) items in the queue.

The strategy applied to the dequeueing (output) processes.

Test whether the queue is empty.

Return the rate of the items that were stored: how many items per time.

Return the rate of the requests for dequeueing the items: how many requests per time. It does not include the failed attempts to dequeue immediately without suspension.

Return the rate of the output items that were dequeued: how many items per time.

Return the wait time from the time at which the item was stored in the queue to the time at which it was dequeued.

See also queueWaitTimeChanged and queueWaitTimeChanged_.

Return the dequeue wait time from the time at which the item was requested for dequeueing to the time at which it was actually dequeued.

See also dequeueWaitTimeChanged and dequeueWaitTimeChanged_.

Return a long-term average queue rate calculated as the average queue size divided by the average wait time.

Dequeue suspending the process if the queue is empty.

Dequeue with the output priority suspending the process if the queue is empty.

Try to dequeue immediately.

Enqueue the item.

Enqueue with the storing priority the item.

Remove the item from the queue and return a flag indicating whether the item was found and actually removed.

Remove the specified item from the queue.

Remove an item satisfying the specified predicate and return the item if found.

Remove an item satisfying the specified predicate.

Clear the queue immediately.

Return the summary for the queue with desciption of its properties and activities using the specified indent.

Signal when the queueNull property value has changed.

Signal when the queueCount property value has changed.

Signal when the queueCount property value has changed.

Signal when the enqueueStoreCount property value has changed.

Signal when the enqueueStoreCount property value has changed.

Signal when the dequeueCount property value has changed.

Signal when the dequeueCount property value has changed.

Signal when the dequeueExtractCount property value has changed.

Signal when the dequeueExtractCount property value has changed.

Signal when the queueWaitTime property value has changed.

Signal when the queueWaitTime property value has changed.

Signal when the dequeueWaitTime property value has changed.

Signal when the dequeueWaitTime property value has changed.

Signal when the queueRate property value has changed.

Signal when the queueRate property value has changed.

Return a signal that notifies when the enqueued item is stored in the internal memory of the queue.

Return a signal that notifies when the dequeuing operation was requested.

Return a signal that notifies when the item was extracted from the internal storage of the queue and prepared for immediate receiving by the dequeuing process.

Signal whenever any property of the queue changes.

The property must have the corresponded signal. There are also characteristics similar to the properties but that have no signals. As a rule, such characteristics already depend on the simulation time and therefore they may change at any time point.
