i build my code like that michael. i modified the class like this
void selectFeatures(double [] posisix, double [] posisiy) {
for (int i=0;i<posisix.length;i++)
{
Geometry point = geomFactory.createPoint(new Coordinate(posisix[i],
posisiy[i]));
...
FeatureIterator<SimpleFeature> iter = selectedFeatures.features();
Set<FeatureId> IDs = new HashSet<FeatureId>();
...
selectedIds.addAll(IDs);
}
displaySelectedFeatures(selectedIds);
}
so in displaySelectedFeatures i have only selectedIds. so how can i get the
IDs within selected so i can set the rule??
"Or if you want to make it more flexible you might give is a Map
argument where the keys are feature IDs and the values are numbers or
names of feature categories that you want to display in separate
colours. It's really up to you."
what do you mean about this?
