ExtJS 5 - How to convert Object to Collection/MixedCollection/HashMap?

Vote count:

0

I have an object on which i would like to perform add/remove/find operation. So i'm just trying to convert that Object as HashMap/Collection object using Ext.util.Collection/Ext.util.MixedCollection/Ext.util.HashMap classes. As it is already an Object i just want to perform typecasting? Is there a straight forward option availble in ExtJS to attain this?

Currently using the following utility method i'm attaining this. Is there any other better option available other than this?

Raw Object:-

  Object {abbreviateValues: true, category: "P", charCode: 13092,charDescription: Array[5], charId: 13092…}

Utility Method:-

convertObjectToCollection: function(rawObject){
  var hashMapObject = Ext.create('Ext.util.HashMap'); 
    for(var key in rawObject) {
      hashMapObject.add(key,rawObject[key]);
    } 
  return hashMapObject;
}

Thanks!
