Examples of freemarker.template.TemplateModelIterator

freemarker.template.TemplateModelIterator
Used to iterate over a set of template models once; usually returned from {@link TemplateCollectionModel#iterator()}. Note that it's not a {@link TemplateModel}.

        return new SimpleScalar(buf.toString());
    }


    public TemplateModelIterator iterator()
    {
        return new TemplateModelIterator()
        {
            private final Iterator it = nodes.iterator();


            public TemplateModel next()
