Accessing class constants

[Kelvin Tan <ke...@relevanz.com>]

I'm running Velocity 1.1. Pretty sure this has been asked before, but
couldn't find a reference to it in the mailing list archives.

Am I able to access class constants directly (ie not through an accessor
method)?

if class Foo has

public static final String HOME = "bar"

am I able to access $foo.HOME, or do I need to add an accessor method?

I looked through the source code, and there's no mention about fields in the
Introspector class, only methods. I could've missed it though.

Apologies. User's Guide.

I think that's the only way, actually.

Sorry, I don't really catch that. In UG?

Do you think it's a better coding practise to include a getter method for
the class constant?

Thanks

I will put this in a FAQ area :)

It's in the archives.

We don't allow you to access class members.

But, there is a little tool called the 'FieldMethodizer' that you would use
like

Context.put("mything", new FieldMethodizer( foo ) );

And then in the template

$mything.HOME

Would work
