The application provides a GUI form for a user to specify one or more search
fields (e.g. land use code, zip code, cultural period, etc). It then highlights
cities (polygon layer) containing archaeological sites that ‘match’ the
criteria. If the user has certain permissions, it also makes the matching
archaeological sites in a point layer visible.
At the moment, the application highlights the cities when the user presses a
‘search’ button. Pressing a second ‘show sites’ button makes the points
visible.

I am not sure I understand the reason to call set style on multiple layers.
Generally you call setStyle on any number of layers as part of setting up your
map for rendering??
There have been experimental renderers that cache feature content (streaming
renderer was faster and easier to maintain). uDig has a multi-threaded renderer
built ontop of the geotools one ...

Thanks Jody.
In my previous email (copied below) I was referring to a variant of the class
StreamingRenderer class.
“I vaguely recall a discussion thread a year or so ago about an experimental /
under-development renderer class that would support updating multiple layers
(i.e. calling setStyle on multiple layers) in a single rendering ‘cycle.’ Does
this ring a bell? If so, can you point me to the source code?”
