Where to put and how to load result object class in Codeigniter?

Question

I'm looking for proper way to organize 'Result object classes' in CodeIgniter. These classes are usualy used in models as described in documentation:

You can also pass a string to result() which represents a class to instantiate for each result object (note: this class must be loaded)

$query = $this->db->query("SELECT * FROM users;");

foreach ($query->result('User') as $row)
{
   echo $row->name; // call attributes
   echo $row->reverse_name(); // or methods defined on the 'User' class
}

So, where to put 'User' class and is there any 'offical' way how to load it?

Try using a library.

Place your class in the application/libraries folder, then use the loader to load it:

$this->load->library('user');

Absolutly not, because that will create new instance of user class and I don't want to have that empty object in memory. And of course, result object classes aren't libraries at all. – sasa Sep 17 '12 at 12:35
The use $this->load file() to load a php file containing your classes – Silviu G Sep 17 '12 at 14:04

Not exactly what you are asking for, but I often use a MY_Model with:

public function merge_object(&$object, $data){

    if (is_object($data)) {
        $data = get_object_vars($data);
    }
    if (!empty($data)) {
        foreach ($data as $property => $value) {
            if (!property_exists($object, $property)) {
                $object->$property = $value;
            }
        }
    }
    return $object;
}

and then call $this->merge_object($this, $data); from the __construct($data = array())

When you call a model function now, it returns a an instance of the model class as well, and so you can access any of its methods. It does essentially what you are trying to do.
