question: private boolean maySkipASI ( CommonToken lastToken , ObservableXtextTokenStream tokens ) { int countDownFrom = lastToken . getTokenIndex ( ) ; for ( int i = countDownFrom - 1 ; i >= 0 ; i -- ) { Token prevToken = tokens . get ( i ) ; if ( prevToken . getChannel ( ) == Token . DEFAULT_CHANNEL ) { if ( mandatoryASI . get ( prevToken . getType ( ) ) ) { return false ; } return true ; } } return true ; }
target:  Prevent ASIs to be skipped at certain locations, e.g. after a return keyword.
