I have a post-grouping relation:
a = { id: chararray, bitmap{ (value_binary: int) } },
where the value_binary tuples are single-element tuples that have been
sorted--the order of the single-element tuples is important. All the "bitmap"
bags are guaranteed to have the same number of single element tuples, but that
number is arbitrary. That is, I can't depend in advance on knowing how many
tuples there will be in "bitmap", but I can depend on each bitmap having the
same number of tuples. An example of an instance with 5 tuples:
9 {(1),(0),(0),(0),(0)}
Would need to become:
9 {(1,0,0,0,0)}
...concatenating those tuples into one tuple, preserving the order, again
without having advance knowledge of how many tuples will be in "bitmap". I
can't figure out how to do it.
Thanks in advance for any suggestions...
Steve
