SystemCollectionsGenericQueue - Core Libraries

Introduction

The SystemCollectionsGenericQueue is a versatile queue implementation available in .NET Core and .NET Framework. It provides efficient and reliable queuing functionality, allowing you to manage asynchronous operations and data streams effectively.

Properties

• size: The number of elements in the queue.
• capacity: The maximum number of elements the queue can hold.
• lock: A lock for thread-safe queue operations.
• is_initialized: Boolean indicating if the queue is initialized.
• dequeue: Returns the element removed from the queue.
• enqueue: Adds an element to the queue.
• isEmpty: Returns true if the queue is empty, false otherwise.

Methods

The queue provides methods for:

• GetSize(): Returns the current queue size.
• GetCapacity(): Returns the current queue's capacity.
• SetLock(): Sets the lock for the queue.
• Enqueue(T item): Adds an item to the queue.
• Dequeue(): Removes and returns the element at the front of the queue.
• isEmpty(): Checks if the queue is empty.

Example

Here's a simple example demonstrating the queue's capabilities:

        
        using System;
        using System.Collections.Generic;

        public class SystemCollectionsGenericQueue
        {
          private readonly List _items = new List();

          public bool IsEmpty() { return _items.Count == 0; }

          public T Get(int index) {
            if (index < 0 || index >= _items.Count) {
              throw new IndexOutOfRangeException("Index out of range");
            }
            return _items[index];
          }

          public void Enqueue(T item) {
            _items.Add(item);
          }

          public T Dequeue() {
            if (_items.Count == 0) {
              throw new InvalidOperationException("Queue is empty");
            }
            return _items.RemoveFirst();
          }
        }
