[antlr-interest]Skipping a Lexer Rule

[Nijesh Panchratna, Noida]

Hi !!

My rule in lexer ignores/skip $Role and doesn't pass it to parser.but it
seems it does pass something else.

The rule is :--
ROLE
:("$Role")+
 (' '|'\t'|'\n' {count++; newline();}|'\r')+
{$setType(Token.SKIP);}
;

Also, I am not clear what happens if my file(parsing file) doesn't contain
this $Role word
i.e I want this rule to execute if there is a $Role word in the file else
skip this rule.How can I achieve this??

thanks in advance.
