[TYPO3-mvc] Ordering of Tx_Extbase_Persistence_ObjectStorage Objects

[Frank Mey - NEW.EGO]

Update:

I solved the problem via a utility class as posted in this list before
(http://lists.typo3.org/pipermail/typo3-project-typo3v4mvc/2010-June/005131.
html).
Only drawback is, that you have to turn the
Tx_Extbase_Persistence_ObjectStorage into an array to 
get a usort, but that is also fine for me and Fluid.

It would be nice if the splObjectStorage could be extended by sorting in the
Extbase core or sth like that,
Because there are many cases you want to combine the power and easiness
fluid/extbase offers to handle
m:n relations on an object-based level without SQL-statements and stuff :). 

If you have questions regarding this utility class and how it should
interact, feel free to ask.

PS: Here is the code of my utility class in Classes/Utility/ArraySort.php :

class Tx_<yourExtensionName>_Utility_ArraySort	{
	
	static public function sortBySeitennummer($array)	{
		usort($array,
'Tx_<yourExtensionName>_Utility_ArraySort::usortBy<yourSortProperty>');

		return $array;
	}
	
	static public function usortBy<yourSortProperty>($a, $b)	{

		return
strnatcasecmp($a->get<your-Property-GetMethod-O-fObject-Stored-In-ObjectStor
age>(),
$b->get<your-Property-GetMethod-O-fObject-Stored-In-ObjectStorage>());
	}
}
