Hi,
We have been using GeoTools 2.7 for several years. The developer, who
handled GeoTools in our application left. My task is to adapt our code to
GeoTools 22.1. Most modifications were straightforward. I struggle with one
piece of code, which is used to implement custom filters:
public static Filter createGeotoolsFilter(final ISimpleFeatureFilter
simpleFeatureFilter) {
FilterFactory2 ff2 = CommonFactoryFinder.getFilterFactory2(null);
UUID key = UUID.randomUUID();
EnvFunction.setGlobalValue(key.toString(), new
CustomFunction.ICustomFunctionImplementation() {
public Object evaluate(Object feature) {
return simpleFeatureFilter.evaluate((SimpleFeature) feature);
}
});
return ff2.equals(ff2.function("custom", ff2.function("env",
ff2.literal(key.toString()))),
ff2.literal(true));
}
The problem is CustomFunction.ICustomFunctionImplementation does no longer
exist in GeoTools 22.1. Is there a simple, straightforward solution to this,
which I can implement locally in that method?
Regards,
Peter
