Examples of freemarker.template.TemplateMethodModel.exec()

freemarker.template.TemplateMethodModel.exec()

Executes the method call. All arguments passed to the method call are coerced to strings before being passed, if the FreeMarker rules allow the coercion. If some of the passed arguments can not be coerced to a string, an exception will be raised in the engine and the method will not be called. If your method would like to act on actual data model objects instead of on their string representations, implement the {@link TemplateMethodModelEx} instead. @param arguments a List of String objectscontaining the values of the arguments passed to the method. @return the return value of the method, or {@code null}. If the returned value does not implement {@link TemplateModel}, it will be automatically wrapped using the {@link Environment#getObjectWrapper() environment object wrapper}.

            TemplateMethodModel targetMethod = (TemplateMethodModel)targetModel;
            List argumentStrings = 
            targetMethod instanceof TemplateMethodModelEx
            ? arguments.getModelList(env)
            : arguments.getValueList(env);
            Object result = targetMethod.exec(argumentStrings);
            return env.getObjectWrapper().wrap(result);
        }
        else if (targetModel instanceof Macro) {
            Macro func = (Macro) targetModel;
            env.setLastReturnValue(null);


        private void testMethod(TemplateHashModel h, int objIdx, int mIdx)
                throws TemplateModelException, AssertionError {
            TemplateMethodModel pv = (TemplateMethodModel) h.get("m" + mIdx);
            final int expected = objIdx * 1000 + mIdx;
            final int got = ((TemplateNumberModel) pv.exec(null)).getAsNumber().intValue();
            if (got != expected) {
                throw new AssertionError("Method assertation failed; " +
                        "expected " + expected + ", but got " + got);
            }
        }
