Sample Usage

var hashmap=require("nativehashmap");
hashmap.add("key", "value");

Its possible to store JSON objects like:

addon.add("object", JSON.stringify({o:"test"}));
console.log(JSON.parse(addon.get("object")).o === "test");

Also you can fetch values Async

addon.add("object", JSON.stringify({o:"test"}));
addon.getAsync("object",function(value){
   console.log(JSON.parse(value).o === "test"); 
});
