Hi guys,
I made few improvements to the GeoServer RESTConfig and sldService stuff
which I would like to briefly discuss here, and in case of interest I can
commit it:
1. DataStoreFileResource: this class originally was intended to let
GeoServer get a shapefile and create a new datastore. I corrected some
errors and changed a bit the behavior. Originally this resource was checking
just for the arrival of a single .shp file, which is not sufficient for my
needs; so I changed it in order to let it accept a ZIP file containing the
whole Shapefile stuff, decompress it into GeoServer data dir, create the new
datastore and contextually create the FeatureType also.
2. FeatureTypeResource: this class allows a user to insert/update a
FeatureType. Originally the resource constrained the user to send the whole
feature type properties everytime. I changed a bit in order to let a user to
update also just some of the properties of the FeatureType if the latter is
already present in the catalog.
3. StyleResource: this resource was incomplete, in particoular it didn't
save the style on the catalog and also didn't check for the style existence
in the case of a replacement. I changed it to perform those tasks.
4. SimpleClient: I put this simple utility class in the test package in
order to allow users to perform simple GET/POST/PUT/DELETE requests to the
REST interfaces. It is not fully complete though.
5. on sldService I added few Resources to let users to easily generate color
classifications and optionally color Ramps, without the need to create and
save a new SLD. Maybe they are redoundant, but very usefull to me. On a POST
request, the user can specify the datasotre, the property, the type of color
quantization to apply and the number of classes. The user can also send as
optional parameters of the form the type of color ramp to generate and in
case of custom color ramp also the start, end and mid colors. The result is
a JSON string representing the quantization rules. Each rule consists
basically of a title, a filter and if the color ramp was specificed a
symbolizer describing the fill to apply.
6. I added to the sldService a UserStyleResource which allows a user to
modify the default SLD of a wms layer, independetly if it is generated from
a featuretype or a coverage. Not yet fully complete though.
Cheers,
Alessio.
