Create an NSComparator to do this. That gives you the full power of
Java to do sorting. I usually make them a public inner class of the
EO I am sorting. Then use the NSArray method
sortedArrayUsingComparator or the NSMutableArray method
sortUsingComparator to sort using an instance of your new
NSComparator subclass.
A trivial example:
/**
* Compares Websites by the site ID.
*/
static class SiteIDComparator extends NSComparator
{
/**
* Compares Websites by the site ID.
*
* @see com.webobjects.foundation.NSComparator#compare
(java.lang.Object, java.lang.Object)
*/
public int compare(Object firstObject, Object secondObject)
throws ComparisonException
{
if ((firstObject == null) || (secondObject == null))
{
throw new NSComparator.ComparisonException("Can't
compare null objects");
}
Website firstSite = (Website)firstObject;
Website secondSite = (Website)secondObject;
return NSComparator.AscendingStringComparator.compare
(firstSite.siteID(),
secondSite.siteID());
}
}

Hi!
This is probably a simple question, but I'm not finding an
answer... how can I sort objects in memory using my own criteria?
The alphabetic ordering is not enough... :)
