Usage

From source file:org.lenskit.gradle.LenskitPlugin.java

public void apply(Project project) {
    final LenskitExtension lenskit = project.getExtensions().create("lenskit", LenskitExtension.class, project);

    for (MetaProperty prop : DefaultGroovyMethods.getMetaClass(lenskit).getProperties()) {
        String prjProp = "lenskit." + prop.getName();
        if (project.hasProperty(prjProp)) {
            Object val = project.findProperty(prjProp);
            String vstr = val != null ? val.toString() : null;
            logger.info("setting property {} to {}", prjProp, val);
            Class type = prop.getType();
            Consumer<Object> set = (v) -> prop.setProperty(lenskit, v);
            if (type.equals(Property.class)) {
                Method m = null;/*w ww.j a  v a 2s .  c om*/
                try {
                    m = lenskit.getClass().getMethod("get" + StringUtils.capitalize(prop.getName()));
                } catch (NoSuchMethodException e) {
                    throw new RuntimeException(e);
                }
                Type t = m.getGenericReturnType();
                Map<TypeVariable<?>, Type> args = TypeUtils.getTypeArguments(t, Property.class);
                Type rt = args.get(Property.class.getTypeParameters()[0]);
                type = TypeUtils.getRawType(rt, Object.class);
                set = (v) -> ((Property) prop.getProperty(lenskit)).set(v);
            }

            if (type.equals(List.class)) {// if the type is list update the val using strtokenizer
                StringTokenizer tok = new StringTokenizer(vstr, StringMatcherFactory.INSTANCE.splitMatcher(),
                        StringMatcherFactory.INSTANCE.quoteMatcher());
                val = DefaultGroovyMethods.toList(tok);
            } else if (type.equals(String.class)) {
                val = vstr;
            } else {
                val = StringConvert.INSTANCE.convertFromString(type, vstr);
            }

            set.accept(val);
        }

    }
