     /**
-     * Neo4j's transactions are not consistent between the graph and the graph
-     * indices. Moreover, global graph operations are not consistent. For
-     * example, if a vertex is removed and then an index is queried in the same
-     * transaction, the removed vertex can be returned. This method allows the
-     * developer to turn on/off a Neo4j2Graph 'hack' that ensures transactional
-     * consistency. The default behavior for Neo4j2Graph is to use Neo4j's native
-     * behavior which ensures speed at the expensive of consistency. Note that
-     * this boolean switch is local to the current thread (i.e. a ThreadLocal
-     * variable).
-     *
-     * @param checkElementsInTransaction check whether an element is in the transaction between
-     *                                   returning it
-     *
      * @deprecated since Blueprints 2.7.0/Neo4j 2.2.x this method is
-     * no longer required since Neo4j indexes no longer return
-     * deleted elements.
+     * no longer required - Neo4j indexes no longer return deleted elements.
