Return the line number of the last character for current token

Is there a way in ANTLR 4 to be able to return the line number of the the last character for the current token ?

I referred Antlr, get last line from token but that would be specific to a rule. I wanted something more generic but couldn't find what would suit me in the ANTLR API.

There is no direct way to get this information. However, if you don't have any -> skip commands in your lexer you can derive it from the following token.

Suppose token b follows token a. If b.getCharPositionInLine()==0, the last character of a is on line b.getLine()-1. Otherwise, the last character of a is on line b.getLine().
