I'm trying to store an object in redis, which is an instance of a class, and thus has functions, here's an example:

function myClass(){

    this._attr = foo;

    this.getAttr = function(){

        return this._attr;

    }

}

Is there a way to store this object in redis, along with the functions? I tried JSON.stringify() but only the properties are preserved. How can I store the function definitions and be able to perform something like the following:

var myObj = new myClass();

var stringObj = JSON.stringify(myObj);

// store in redis and retreive as stringObj again

var parsedObj = JSON.parse(stringObj);



console.log(myObj.getAttr()); //prints foo

console.log(parsedObj.getAttr()); // prints Object has no method 'getAttr'

How can I get foo when calling parsedObj.getAttr()?

Thank you in advance!

EDIT

Got a suggestion to modify the MyClass.prototype and store the values, but what about something like this (functions other than setter/getter):

function myClass(){

    this._attr = foo;

    this._accessCounts = 0;

    this.getAttr = function(){

        this._accessCounts++;

        return this._attr;

    }

    this.getCount = function(){

        return this._accessCounts;

    }

}

I'm trying to illustrate a function that calculates something like a count or an average whenever it is called, apart from doing other stuff.
