Thanks Jody. I'm dealing with only tens of features here, so it's no big
problem to read them into memory, then sort. So, you're saying that to do
this with geotools, I would need an implementation of the FeatureList
interface?

Sorting is not supported in 2.1.0, we have the API in 2.2.x but I do not
think anyone has implemented
a useful SQL based solution for the database datastores.
The initial focus is shapefile, and presenting a random access api (aka
FeatureList) for shapefile. There
is the Filter 1.1 sortBy constructs in the code base, and a start in the
direction of sorting.
I hope that makes sense? A FeatureCollection is unsorted, a FeatureList
has an order and thus can be sorted. I had also thought about
using a TreeSet but did not get any feedback either way ...
Cheers,
Jody
