Examples of com.sleepycat.je.tree.IN.fetchTarget()

com.sleepycat.je.tree.IN.fetchTarget()
Returns the target of the idx'th entry or null if a pendingDeleted or knownDeleted entry has been cleaned. Note that null can only be returned for a slot that could contain a deleted LN, not other node types and not a DupCountLN since DupCountLNs are never deleted. Null is also returned for a KnownDeleted slot with a NULL_LSN. @return the target node or null.

                         * See if we need to descend further.  If fetchTarget
                         * returns null, a deleted LN was cleaned.
                         */
                        Node n = null;
                        if (!in.isEntryKnownDeleted(index)) {
                            n = in.fetchTarget(index);
                        }


                        if (n != null && n.containsDuplicates()) {
