Hi,
this feature has been desired for a long while,
http://jira.codehaus.org/browse/GEOS-822 (ok, the ticket is more generic,
not restricted
to WMS).
I concur with Jody, please to try keep the configuration in the WFSInfo
object.
About the implementation, I can see two possible paths:
* Use, as suggested in GEOS-822, a extension filter to disable certain
output format implementations.
The upside of this is simplicity of configuration, there are less classes
than output formats.
The drawback of this approach is that some output formats implement
multiple mime types, e.g., PNG and PNG8
* Use a custom dispatcher callback and control the output format parameter
directly, the advantage is that you
can control with detail what is enabled, the disadvantage is that might
end up having the user disable aliases
of particular formats, for example, to turn off png output one has to
disable both PNG and image/png
In all cases some GUI having checkboxes would be recommended, only the code
knows the full list of supported format
names, and I'm afraid some are only known inside the class, but not
advertised, you might have to work a bit on that too
(or make the list be a whitelist)
For example, kml works with both "application/vnd.google-earth.kml+xml" and
"application/vnd.google-earth.kml xml" because
browsers tend to escape + and make it a space...
Cheers
Andrea
