[antlr-interest] How to conditionnally ignore tokens in Parser

Hi,
I'm using ANTLR to update java files, replacing certain methods with regenerated ones.
Currently, the operation cuts everything between the METHO_DEF and the next "field". This
eats any comment in-between and doesn't behave nicely when the method is the last field
of the class.
{Writing this, the solution came: keep the RCURLY to remember the proper position.}
I know the Lexer can SKIP or filter unwanted tokens, a stream could discard or hide them.
But can the Parser ignore certain tokens most of the time and process them only in certain
rules? Is there a way for a rule to pull out hidden tokens and process them?
