Methods

LinkedList();

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();

Constructor

init(c: {new (data: any): T;}, init_data?: Array<any>): void

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType);

or

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);

Init list, with or without initial data

addElem(data: any, ll?: LinkedList<T>): LinkedList<T>`

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.addElem('data4');

Add an element at the right of the list, alias of addElemRight

addElemRight(data: any, ll?: LinkedList<T>): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.addElemRight('data4');

Add an element at the right of the list

addElemLeft(data: any, ll?: LinkedList<T>): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.addElemLeft('data4');

Add an element at the left of the list

removeElem(elem?: T): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
//
var listElem:ElemenType = ll.get();
ll.removeElem(listElem);
//
// or
//
ll.removeElem();

Remove current element or a specified one

removeElemByPos(pos: number): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.removeElemByPos(1);

Remove element by position in the list

removeElemByData(data: any): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.removeElemByData('data2');

Remove element by data

insertElem(data: any, pos?: number): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.insertElem('data2', 1);

Add element at the specified position, without position the element will be added at the start of the list like addElemLeft`

length(): number`

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.length(); // return 3

Return the length of the list

toStart(): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.toStart();

Move the internal pointer to the head of the list

toNext(): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.toNext();

Move the internal pointer to the next element with rispect to the current element

toPrev(): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.toPrev();

Move the internal pointer to the previous element with rispect to the current element

toEnd(): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.toEnd();

Move the internal pointer to the end of the list

get(): T

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.get();

Return the current element

isStart(elem?: T): boolean

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
//
var listElem:ElemenType = ll.toNext().get();
ll.isStart(listElem);

Check if the passed element is the head of the list

isEnd(elem?: T): boolean

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
//
var listElem:ElemenType = ll.toNext().get();
ll.isStart(listElem);

Check if the passed element is the end of the list

clone(return_cloned?: boolean): LinkedList<T>

var ll:LinkedList<ElementType> = new LinkedList<ElementType>();
ll.init(ElementType, ['data1', 'data2', 'data3']);
ll.clone();
//
// or
//
var ll_cloned:LinkedList<ElementType> = ll.clone(true);

Clones the list, by default the reference of the cloned list will be stored in the cloned_list, if true value will be passed the refence will return directly
