Sigh... the memory preloading was a thing I did develop in a branch
a few years ago to show that streaming rendering could be just as
fast as J2DRenderer if you preloaded in memory and spatially indexed the
geometries.
Unfortunately, that was just a proof of concept and was not intended
to be ported to the production version of geotools, but someone
did port it anyways... Long story short, it works only for a single
layer, because that what I needed for that demo...
Now, fixing IndexedFeatureResults so that it can become a generally
usable class would not be that difficult, but I really have no
time at the moment to work on it. I can try to have a peek at
it during the weekend if you can wait.
Cheers
Andrea
