[antlr-interest] detecting rubbish data at end of input

Hello,

When using grammars written in ANTLR, the parser correctly recognizes 
data from an input stream, but if I have some rubbish text at the end of 
the input (which rubbish text is not supposed to be parsed by the grammar) 
the parser does not complain.

I guess this behavior is all right (I mean the parser did its job and parsed 
whatever I said it should parse), but is there any trick to detect when there 
is any data left in the input after the parser has done its job? 

Thanks,
Gabi.
