Examples of freemarker.template.TemplateMethodModelEx

freemarker.template.TemplateMethodModelEx
"extended method" template language data type: Objects that act like functions. Their main application is calling Java methods via {@link freemarker.ext.beans.BeansWrapper}, but you can implement this interface to create top-level functions too. They are "extended" compared to the deprecated {@link TemplateMethodModel}, which could only accept string parameters.
In templates they are used like {@code myMethod(1, "foo")} or {@code myJavaObject.myJavaMethod(1, "foo")}.

        
        TemplateModel a = e.get("A");
        assertTrue(a instanceof TemplateScalarModel);
        assertTrue(a instanceof TemplateHashModel);
        assertEquals(((TemplateScalarModel) a).getAsString(), "ts:A");
        TemplateMethodModelEx nameMethod = (TemplateMethodModelEx) ((TemplateHashModel) a).get("name");
        assertEquals(((TemplateScalarModel) nameMethod.exec(new ArrayList())).getAsString(), "A");
        
        assertSame(e, enums.get(E.class.getName()));
        
        bw.clearClassIntrospecitonCache();
        TemplateHashModel eAfterClean = (TemplateHashModel) enums.get(E.class.getName());
