Just what I asked Tim :-).  There are as many as six functions --
difference, union, intersection, weightedUnion, weightedIntersection,
and multiunion.  The functions operate on sets; they accept any of XY
family of objects.  So it's not obvious what they would be methods
of.  Each object -- Set, TreeSet, Bucket, BTree -- could get a copy of
the code, but that seems a little silly.
