ts-collection/lib/util/queue.d.ts

This is re-write of the java collection classes in typescript. There is some tweak as typescript templates are not as equivalent as Java.

import { Collection } from "./collection";
export interface Queue<E> extends Collection<E> {
    enqueue(e: E): boolean;
    offer(e: E): boolean;
    dequeue(): E;
    poll(): E;
    /**
     * Retrieves but does not remove head of the queue.
     * This method throws an exception if the queue is empty.
     */
    element(): E;
    /**
     * Retrieves but does not remove the head of the queue. This method
     * does not throws an exception if the quere is empty, returns null.
     */
    peek(): E;
}
