Examples of freemarker.template.ObjectWrapper.wrap()

freemarker.template.ObjectWrapper.wrap()

Makes a {@link TemplateModel} out of a non-{@link TemplateModel} object, usually by "wrapping" it into a{@link TemplateModel} implementation that delegates to the original object. @param obj The object to wrap into a {@link TemplateModel}. If it already implements {@link TemplateModel}, it should just return the object as is. @return a {@link TemplateModel} wrapper of the object passed in. To support un-wrapping, you may consider thereturn value to implement {@link WrapperTemplateModel} and {@link AdapterTemplateModel}. The default expectation is that the {@link TemplateModel} isn't less thread safe than the wrapped object.If the {@link ObjectWrapper} returns less thread safe objects, that should be clearly documented, as itrestricts how it can be used, like, then it can't be used to wrap "shared variables" ( {@link Configuration#setSharedVaribles(Map)}).

        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 ) {

        Class clazz = this.clazz != null ? this.clazz : object.getClass();

        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 ) {
