Hi Andy,
it seems like an awful amount of work the way you do it. I actually got it
to work using filters, and it works really well. Takes a little bit to get
a handle on working with filters,
but once you do, it’s very spiffy! Here is my code:
public static Style createDefaultAssetsExposureStyle(GeometryDescriptor
gd) {
PropertyIsEqualTo filterIrrelevant =
ff.equals(ff.property("EXPOSURE"),
ff.literal(-1));
Rule ruleIrrelevant = createDefaultStyleRule(gd, Color.GRAY);
ruleIrrelevant.setFilter(filterIrrelevant);
PropertyIsEqualTo filterAffected =
ff.equals(ff.property("EXPOSURE"),
ff.literal(1));
Rule ruleAffected = createDefaultStyleRule(gd, Color.RED);
ruleAffected.setFilter(filterAffected);
PropertyIsEqualTo filterNotAffected =
ff.equals(ff.property("EXPOSURE"),
ff.literal(0));
Rule ruleNotAffected = createDefaultStyleRule(gd, Color.GREEN);
ruleNotAffected.setFilter(filterNotAffected);
FeatureTypeStyle fts = sf.createFeatureTypeStyle();
fts.rules().add(ruleIrrelevant);
fts.rules().add(ruleAffected);
fts.rules().add(ruleNotAffected);
Style style = sf.createStyle();
style.featureTypeStyles().add(fts);
return style;
}
public static Rule createDefaultStyleRule(GeometryDescriptor gd, Color
fillColor) {
Symbolizer symbolizer = null;
Fill fill = null;
Class<?> geomType = gd.getType().getBinding();
String geometryAttributeName = gd.getLocalName();
Stroke stroke = sf.createStroke(ff.literal(Color.BLACK),
ff.literal(1.0f));
if (LineString.class.isAssignableFrom(geomType) ||
MultiLineString.class.isAssignableFrom(geomType)) {
symbolizer = sf.createLineSymbolizer(stroke,
geometryAttributeName);
} else if (Polygon.class.isAssignableFrom(geomType) ||
MultiPolygon.class.isAssignableFrom(geomType)) {
fill = sf.createFill(ff.literal(fillColor),
ff.literal(OPACITY));
symbolizer = sf.createPolygonSymbolizer(stroke, fill,
geometryAttributeName);
} else {
fill = sf.createFill(ff.literal(fillColor),
ff.literal(OPACITY));
Mark mark = sf.getCircleMark();
mark.setFill(fill);
// mark.setStroke(stroke);
Graphic graphic = sf.createDefaultGraphic();
graphic.graphicalSymbols().clear();
graphic.graphicalSymbols().add(mark);
graphic.setSize(ff.literal(POINT_SIZE));
symbolizer = sf.createPointSymbolizer(graphic,
geometryAttributeName);
}
Rule rule = sf.createRule();
rule.symbolizers().add(symbolizer);
return rule;
}
