namespace My\Shitty;
use \Exception;
```

# Class: Thing

It is a thing that holds stuff.  Takes an array in the constructor in which to put stuff; doesn't care if it's empty or not.

```
class Thing {
    protected $stuff;
```

## Constructor

This makes the thing that holds stuff.  Takes an array.  This whole idea is not working out as well as I thought it would.

```
    public function __construct(array &$stuff) {
        $this->stuff = $stuff;
    }
```

## Method: addStuff($key, $val)

Takes a key and a value and puts them in stuff.  Will return the previous value of $key if any, null if not.

```
    public function addStuff($key, $val) {
        $ret = null;
        if(array_key_exists($key, $this->stuff)) {
            $ret = $this->stuff[$key];
        }
        $this->stuff[$key] = $val;
        return $ret;
    }
```

## Method: getStuff($key)

Get something from stuff.

```
    public function getStuff($key) {
        if(!array_key_exists($key, $this->stuff)) {
            throw new Exception('BAD.  BAD DOG.  BAD. DOG.');
        }
        return $this->stuff[$key];
    }
}
