Hi Michelle,
Let me get this straight: you have an array of ScalarMaps, and you want to
know which ScalarMap in the array is a mapping from "index" to something?
What is wrong with iterating through your array, looking for the correct
map? This is only O(N) complexity where N is the number of mappings, and
I highly doubt you have more than 10-15 mappings at most!
If you *must* determine the index in advance, then when you are creating
the mappings, save an integer indicating where the index mapping is.
Unless I am misunderstanding your question, this is a basic programming
problem with a very simple solution; not a VisAD problem.
