The CachedRowSet lacks a count method, but there are first, last,
beforeFirst, and afterLast methods that move the cursor, and next (or
prev) to step through. To simulate count, I move to last and then getRow
to see how many there are.
To create a blank CachedRowSet, I discovered you can select for a record
that you know isn't there to create an empty (but perfectly valid) set.
Though, the docs imply you could also do this programtically, perhaps
with the RowSetReader.
I don't know where the source code is either, or if it's available.
Perhaps we need to write our own implementation ;-)
