Hi Kamen,

we have used the array-index in an application that stored map locations referenced by a coordinate. The coordinate is stored in x and y slots of the objects, and we wanted to retrieve objects by coordinate, without writing a special purpose index for the application.

The array-index class is only good to index objects with multiple slots that have integral values. There is nothing I can see that precludes other multiple-slot indices which would accept string values, but that would be more involved to implement.

The dimensions of the index array are required to set up the array that holds the index.

I hope that this answers your question.

Cheers, Hans
