note 102348 added to class.arrayobject

The note above posted by tony at tonyandcarol dot com could be improved adding the methods:

function getCollection()
{
		return $this->data;
}
	
function exists($_id)
{
		if($_thisObject = $this->data->offSetExists($_id))
		return true;
		else
		return false;		
}

The first one might be useful to call an iterator:

$iterator = $myCollection->getCollection()->getIterator();

while($iterator->valid()) 
{
    echo $iterator->key() . ' => ' . $iterator->current()->getObject() . "\n";

    $iterator->next();
}

The second one might be useful to control the function addObject($_id, $_object).

if($myCollection->exists($key))
$myCollection->addObject($key,$myCollection->getObject($key)+1);
else
$myCollection->addObject($key, 1);
