Hi Vijay,
You could grab all matched text in the `@after` block using the `getText()`
method:
COMMENT
@init{
boolean isJavaDoc = false;
System.out.println("Entering comment");
}
@after {
System.out.println("Leaving comment, matched: " + getText());
}
: '/*'
{
if((char)input.LA(1) == '*') {
isJavaDoc = true;
}
}
(options {greedy=false;} : . )*
'*/'
;
Regards,
Bart Kiers.
