Examples of org.geotools.styling.AbstractStyleVisitor

org.geotools.styling.AbstractStyleVisitor
A basic implementation of the StyleVisitor interface.
This class implements the full StyleVisitor interface and visits all components of a style object tree.

        assertTrue(style.isPresent());


        transformer.transform(style.get()); // assert it can be converted to SLD


        final List<Rule> rules = Lists.newArrayList();
        style.get().accept(new AbstractStyleVisitor() {
            @Override
            public void visit(Rule rule) {
                rules.add(rule);
            }
        });
