aha I remembered the class I was interested in – JLayeredMapPane.  My hope was 
that this class would allow my application to ‘restyle’ multiple layers as 
noted below.

 

The Javadoc states “This class is not usable yet !”  I may have time to work on 
this.  I saw Jira issue 3780; does a to-do list for what remains to be 
implemented exist?

 

Thanks,

Hal

Applications can update the map styles in any way they see fit :)

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?”
