Hello,
while testing some gated semantic predicate:
address
@init{int n=1;}:
( {n<=12}?=> c=CHAR {n++;} )+
{
// check for address validity
final String t = $address.text;
if( t.length() != 12 ) {
throw new InvalidSWIFTBlock1AddressException( t,
$c.getLine(), $c.getCharPositionInLine() );
}
}
;
catch[MismatchedTokenException mte] { throw new
InvalidSWIFTBlock1AddressException( mte.token.getText(), mte.line,
mte.charPositionInLine ); }
I encoutered problem after Java source generation:
class DFA1 extends DFA {
public DFA1(BaseRecognizer recognizer) {
this.recognizer = recognizer;
this.decisionNumber = 1;
this.eot = DFA1_eot;
this.eof = DFA1_eof;
this.min = DFA1_min;
this.max = DFA1_max;
this.accept = DFA1_accept;
this.special = DFA1_special;
this.transition = DFA1_transition;
}
public String getDescription() {
return "()+ loopback of 67:1: ({...}? =>c= CHAR )+";
}
public int specialStateTransition(int s, IntStream _input) throws
NoViableAltException {
TokenStream input = (TokenStream)_input;
int _s = s;
switch ( s ) {
case 0 :
int LA1_23 = input.LA(1);
int index1_23 = input.index();
input.rewind();
s = -1;
if ( (LA1_23==CHAR) ) {s = 24;}
else if ( (LA1_23==12) && ((n<=12))) {s = 14;}
The Java compiler says:
SWIFTMTParser.java:865: cannot find
symbol
symbol : variable n
location: class
com.bnpparibas.acetp.foxhound.spec2009.parser.SWIFTMTParser.DFA1
else if ( (LA1_23==12) && ((n<=12))) {s = 14;}
I've tried to modify something using -Xminswitchalts 100 but I don't know
what to do to correct this issue.
Is it a known antlr bug?

Loïc
