Examples of freemarker.template.ObjectWrapper

freemarker.template.ObjectWrapper
Maps Java objects to the type-system of FreeMarker Template Language (see the {@link TemplateModel}interfaces). Thus this is what decides what parts of the Java objects will be accessible in the templates and how.
For example, with a {@link BeansWrapper} both the items of {@link Map} and the JavaBean properties (the getters)of an object are accessible in template uniformly with the {@code myObject.foo} syntax, where "foo" is the map key orthe property name. This is because both kind of object is wrapped by {@link BeansWrapper} into a{@link TemplateHashModel} implementation that will call {@link Map#get(Object)} or the getter method, transparentlyto the template language. @see Configuration#setObjectWrapper(ObjectWrapper)

    @Override
    public Representation toRepresentation(Object object) {
   
        Class clazz = this.clazz != null ? this.clazz : object.getClass();
        Configuration configuration = createConfiguration(object, clazz);
        final ObjectWrapper wrapper = configuration.getObjectWrapper();
        configuration.setObjectWrapper(new ObjectWrapper() {
            public TemplateModel wrap(Object obj) throws TemplateModelException {
                TemplateModel model = wrapper.wrap(obj);
                if ( model instanceof SimpleHash ) {
                    SimpleHash hash = (SimpleHash) model;
                    if ( hash.get( "page" ) == null ) {
                        PageInfo pageInfo = (PageInfo) request.getAttributes().get( PageInfo.KEY );
                        if ( pageInfo != null ) {
