Accessing enum literals in Generator [message #1063971]

I have the following grammar:

Model:
	greetings+=Greeting*;
	
enum Boolean:
	True = 'not' |
	False = 'real'
;

Greeting:
	'Hello' name=ID state=Boolean 'human' '!';

In my generator file, I want to compare the value of "state" to the literal value of the Boolean enum. Basically, I was looking for something like this:

if (state.compareTo(Boolean.True))

What is the equivalent for it in Xtend?

Hi,

is there a reason to use an enum?

Greeting:'Hello' name=ID ('real' | state?='not') 'human' '!';
