Retrieving arguments

[wat3r...@gmail.com]

Hi All,

Is there any way to retrieve all of the arguments from a template file?

Thanks,

Maria

If you are inside the template, you can find all template argument names by calling @__renderArgTypeMap() method, here is the method signature:

protected Map<String, Class> __renderArgTypeMap()

Once you get the Map, the keySet() is your argument names, and you can use @__get("varName") to retrieve the argument value by name

Great! Using that method worked! Thanks.

Sorry to open this again.... But, I wasn't trying to get the values of arguments before and didn't test for it. I was able to get the map for arguments and their types. Each argument has a default value. When I try to invoke __get("key"), I always get null. So, I'm doing this all using reflection.

Method getMethod = TemplateBase.class.getDeclaredMethod("__get", String.class);

getMethod.setAccessible(true);

Object o = getMethod.invoke(template, key);

I'm not sure what I'm missing. Any ideas?

You can't get default value using this method. Only passed in argument values can be retrieved. And I don't think it is a good idea to return default value in that __get method because it will slow down the template performance a lot

Oh ok, what is the best way to get the default value? Or it cannot be retrieved at all?

The best way is to reference by their name.  E.g

@args String foo = "bar"

...

@foo @// output bar here

Is there a way to do that programmatically and not on the template itself?
