freemarker.core.ast.TemplateElement
Objects that represent elements in the compiled tree representation of the template necessarily descend from this abstract class.

    static public Template getPlainTextTemplate(String name, String content, 
            Configuration config) {
         Template template = new Template(name, config, NULL_CODE_SOURCE);
        final char[] text = content.toCharArray();

          public void execute(Environment env) throws IOException {
            env.getOut().write(text);
          }
        });
        DebuggerService.registerTemplate(template);
