A method for mapping index values corresponding to a data structure to data storage location values, the method comprising:

• receiving a notification containing one or more changes to a parent data structure, wherein the data structure depends on the parent data structure for updates, and wherein the one or more changes include one or more of additions, modifications, deletions, or re-indexing, and wherein the notification includes one or more of new index values or new data storage location values;
• updating the data structure based on one or more of the one or more changes to the parent data structure, wherein the updating includes modifying one or more of the index values or the data storage location values based on the new index values and the new data storage location values;
• and
• notifying one or more child data structures of the updating of the data structure, wherein the one or more child data structures depend on the data structure, and wherein the notifying includes sending the one or more of the modified index values or the modified data storage location values to the one or more child data structures, and wherein the notifying is implemented using one or more listeners associated with the one or more child data structures and the data structure.
