Felix Knecht updated DIRSERVER-1294:
------------------------------------

    Attachment: size_has.patch

Just what I already have so far. I don't want to keep it trailing around somewhere I may not rememeber the place ...
(Code doesn't covers all Cursor implementations, there'll exist compile errors after applying the patch which needs your attention and implementation)

> The cursor implementation currently does not have the size() and hasNext() methods. They would be very helpful in ma,ny places.
> For instance, the paged search control requires that the response control contains the expected size. The hasNext() method could help to avoid a next() and previous() calls to check if we have one more entry available in the cursor.
