Examples of org.geotools.process.function.ProcessFunction

org.geotools.process.function.ProcessFunction
A wrapper allowing a {@link Process} with a single output to be called as a {@link Function}. Since Function parameters are positional and Process parameters are named, the following strategy is used to allow specifying named Process parameters as function inputs. All inputs to the function must evaluate to Map, with a single entry where the key is the name of a process parameter and the value is the argument value @author Andrea Aime - GeoSolutions

            for (FeatureTypeStyle featureTypeStyle : featureTypeStyles) {


                // Getting the main transformation
                Expression transformation = featureTypeStyle.getTransformation();
                if (transformation instanceof ProcessFunction) {
                    final ProcessFunction processFunction = (ProcessFunction) transformation;
                    final String processName = processFunction.getName();


                    // Checking whether the processFunction is a DynamicColorMapProcess
                    if (processName.equalsIgnoreCase(DynamicColorMapProcess.NAME)) {
                        return getColorRampDefinition(processFunction);
                    }
