Hi Mihaja,
Unfortunately, I do not believe there is a CQL function to determine if
a geometry is valid or not. In some sense, this is ok as there is no
way for a database or datastructure to optimize searching for the
geometries which are broken.
That said, you should be able to use the JTS Geometry.isValid function
to help.
Try something like...
SimpleFeatureCollection features = source.getFeatures(); // no need to
filter; we will look at each geometry.
for (SimpleFeature feature : features) {
Geometry geometry = (Geometry) feature.getDefaultGeometry();
if (!geometry.isValid()) {
//Do something with the valid geometries. Add to feature
collection for display?
}
}
Hopefully that helps; let us know if you have any questions.
Cheers,
Jim

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
