If I got you right I am to create my own cursor object which retrieves and stores the array with the items I want to deliver. The cursor then implements the next and get method in order to send the array one by one. But where is the cursor being called ? I tried to base my own partition on the abstract btree partition but what am I supposed to return from getRootId and getDefaultId and even worse from convertAndInit ? Sorry for the beginner level questions but ApacheDS is quite complex and new to me.
