Question

I have a class that performs database operations and returns results (array, true, false). And I have an another class that creates JSON string by using this class in its constructor.
Can we say this class is an Adapter? Or simply wrapper or …

Class Db
{
    public function getRows($params)
    {
        //...
    }
}


Class DbAdapter
{
    private $_dbh;
    public function __construct($dbh)
    {
        $this->_dbh = $dbh;
    }

    public function getJson()
    {
        return '{"key": "foo", "key2": ' . json_encode($this->_dbh->getRows($params)) . '}';
    }
}

Thanks
