Description

Node

A node is a vertex in the list, implemented in the DLNode class and has three fields:

|Field|Type|Getter|Setter|Description| |-|-|-|-|-| |data|T (generic)|Yes|Yes|Data object contained in the node.| |next|DLNode | null|Yes|Yes|Reference to next node, null if its last node.| |preious|DLNode | null|Yes|Yes|Reference to previous node. null if its first node.|

Doubly Linked List

The doubly linked-list implementation is present in the DoublyLinkedList class. It has three fields:

|Field|Type|Getter|Setter|Description| |-|-|-|-|-| |length|number|Yes|No|Number of nodes present in the list.| |start|DLNode | null|Yes|Yes|Reference to start node, null if list is empty.| |end|DLNode | null|Yes|Yes|Reference to last node. null if list is empty.|

Demo

import { DoublyLinkedList, DLNode } from "./node_modules/dl-doubly-linked-list";

let list : DoublyLinkedList<any> = new DoublyLinkedList();

let nodes : DLNode<any>[] = [];
for(let i=0; i<10; i++) {
    nodes[i] = new DLNode(); 
    nodes[i].data = i * i;
    list.insertStart(nodes[i]);
}

// Inserting new node at the end
let newNode : DLNode<any> = new DLNode();
newNode.data = 300;
list.insert( newNode, 6 );

// Deleting a node
list.delete(4);

// Get array of the nodes
let array = list.toArray();

console.log(array);
