Queue/Usage: Difference between revisions

E also has queues in the standard library such as <code>&lt;import:org.erights.e.examples.concurrency.makeQueue></code>, but they are designed for concurrency purposes and do not report emptiness but rather return a promise for the next element.

// Create a queue and "push" items into it

// "Pop" items from the queue in FIFO order

// To tell if the queue is empty, we check the count

// If we try to pop from an empty queue, an exception

// is thrown.
