Using Vector in Java script

Question

I got this vector class from some website for implementation of vector in java script
function Vector(inc) {
     if (inc == 0) {
          inc = 100;
     /* Properties */
     this.data = new Array(inc);
     this.increment = inc;
     this.size = 0;
     /* Methods */
     this.getCapacity = getCapacity;
     this.getSize = getSize;
     this.isEmpty = isEmpty;
     this.getLastElement = getLastElement;
     this.getFirstElement = getFirstElement;
     this.getElementAt = getElementAt;
     this.addElement = addElement;
     this.insertElementAt = insertElementAt;
     this.removeElementAt = removeElementAt;
     this.removeAllElements = removeAllElements;
     this.indexOf = indexOf;

     this.resize = resize;
     this.toString = toString;
     this.sort = sort;
     this.trimToSize = trimToSize;
     this.clone = clone;
     this.overwriteElementAt;
// getCapacity() -- returns the number of elements the vector can hold
function getCapacity() {
     return this.data.length;
// getSize() -- returns the current size of the vector
function getSize() {
     return this.size;
// isEmpty() -- checks to see if the Vector has any elements
function isEmpty() {
     return this.getSize() == 0;

function getLastElement() {
     if (this.data[this.getSize() - 1] != null) {
          return this.data[this.getSize() - 1];

function getFirstElement() {
     if (this.data[0] != null) {
          return this.data[0];
// getElementAt() -- returns an element at a specified index
function getElementAt(i) {
     try {
          return this.data;
     catch (e) {
          return "Exception " + e + " occured when accessing " + i;     
// addElement() -- adds a element at the end of the Vector
function addElement(obj) {
     if(this.getSize() == this.data.length) {
          this.resize();

          return "Invalid index " + i;

function removeElementAt(index) {
     try {
          var element = this.data[index];
          for(var i=index; i<(this.getSize()-1); i++) {
               this.data[i] = this.data[i+1];
          this.data[getSize()-1] = null;
          this.size--;
          return element;
     catch(e) {
          return "Invalid index " + index;
// removeAllElements() -- removes all elements in the Vector
function removeAllElements() {
     this.size = 0;
     for (var i=0; i<this.data.length; i++) {
          this.data[i] = null;
// indexOf() -- returns the index of a searched element
function indexOf(obj) {
     for (var i=0; i<this.getSize(); i++) {
          if (this.data[i] == obj) {
               return i;
     return -1;
// contains() -- returns true if the element is in the Vector, otherwise false

     this.data = newData;
// trimToSize() -- trims the vector down to it's size
function trimToSize() {
     var temp = new Array(this.getSize());
     for (var i = 0; i < this.getSize(); i++) {
          temp[i] = this.data[i];
     this.size = temp.length - 1;
     this.data = temp;
// sort() - sorts the collection based on a field name - f
function sort(f) {
     var i, j;
     var currentValue;
     var currentObj;
     var compareObj;

// clone() -- copies the contents of a Vector to another Vector returning the new Vector.
function clone() {
     var newVector = new Vector(this.size);
     for (var i=0; i<this.size; i++) {
          newVector.addElement(this.data[i]);
     return newVector;
// toString() -- returns a string rep. of the Vector
function toString() {
     var str = "Vector Object properties:\n" +
     "Increment: " + this.increment + "\n" +

     "Elements:\n";
     for (var i=0; i<getSize(); i++) {
          for (var prop in this.data[i]) {
               var obj = this.data[i];
               str += "\tObject." + prop + " = " + obj[prop] + "\n";
     return str;     
// overwriteElementAt() - overwrites the element with an object at the specific index.
function overwriteElementAt(obj, index) {
     this.data[index] = obj;
Now I have written this code .This code is written using API'sfunction getOptions(ctx)
var options="";
var subroles = ctx.getAdminRole().getAttributeMultiValue("CUSTOM10");
var v = new Vector(subroles);
options = v.getElementAt(0);
Now suppose the function getAttributeMultivalue is returning RoleA,RoleB
Now i want RoleA to be stored in getElementAt(0) and RoleB in getElementAt(1)
But with the above code i am getting RoleA,RoleB in getElementAt(0)

well the question is also about Vector class of JavaNo it is not you doofus. It is about JavaScript. Your question has fuck all to do with Java.
so I thought to post it here.That was a mistake.
any ways if you don't know java script or anything about vector class then you should not reply.I know about JavaScript.
I know about Vectors.
I will not tell you anything about JavaScript here.
I wouldn't tell you anything useful anyway because I have taken a personal dislike to you.

No need to make me understand what is the purpose of this forum.Really? Because you don't seem to get it. At all.
next time take care before you reply.Next time engage your tiny pea brain in some sort of logical thought before posting.
