map-linked-list

Node core linked list module converted to use a map.

I know this somewhat defeats the purpose of a linked list, but the aim was to have a linked list without modifying the original objects the way that Node's version does.

Install

$ npm install --save map-linked-list

Test

$ npm test

Example

'use strict'
 
const L = require('map-linked-list')
 
const list = { name: 'list' }
const a = { name: 'a' }
const b = { name: 'b' }
L.init(list)
L.init(a)
L.init(b)
 
L.append(list, A)
// L.get(A) === L.peek(list)

API

L.init(list)

Creates the underlying map for the given list.

Note: You will leak memory if you do not (at some time) L.destroy(_list_).

L.get(list)

Returns the Item map for the given list.

L.destroy(list)

Cleans up the underlying map for the given list.

L.peek(list)

Returns the Item for the given list. To access the original object passed to L.init, use the _item property.

L.remove(item)

Removes the given item, but does not cleanup the underlying Item.

L.shift(list)

Similar to Array#shift. Removes and returns the previous Item. Note: does not cleanup the underlying Item.

L.append(list, item)

Removes item from the list and appends it to the end.

L.isEmpty(list)

Returns boolean for whether the list is empty.
