Thanks Ian, that's of great help. !
So far, I crafted a categorized style this way:
================================================
Graphic graphic = sf.getDefaultGraphic();
Mark mark = sf.getCircleMark();
List<Expression> categories = new ArrayList<>();
categories.add(ff.property("value"));
for (int i = 0; i < colors.length; ++i) {
categories.add(ff.literal(thresholds[i]));
categories.add(ff.literal(FormatUtils.colorToHashedHexs(colors[i])));
}
Function ctgFun = new CategorizeFunction(categories,
ff.literal("#0000FF")); // FIXME remove fallback
mark.setFill(sf.createFill(ctgFun, ff.literal(fillOpacity)));
// mark.setStroke(sf.createStroke(
// ff.literal(color), ff.literal(strokeOpacity)));
graphic.graphicalSymbols().clear();
graphic.graphicalSymbols().add(mark);
PointSymbolizer ps = sf.createPointSymbolizer(graphic,
GEOM_PROPERTY);
================================================
