The data source doesn't have to be a SimpleFeatureCollection - that
was the example I used because (I think) it was mentioned a few posts
ago.
If you are working with a FeatureSource you can apply your filter to
it and make your Layer with the results...
public Layer createNewLayer(SimpleFeatureSource source,
String filterString, Style style) {
try {
Filter filter = CQL.toFilter(filterString);
return new FeatureLayer(featureSource.getFeatures( filter ), style);
} catch (Exception ex) {
throw new RuntimeException(ex);
}
}
Note, this example doesn't save the filter results as a new feature
collection in your code but you can do that if you want as was done in
the example in the previous post.
The Query tutorial is a good one to look at if you haven't already:
