A problem with loading AST Node type occured.
Here is my simplest grammar:
primaryExp
:
INTEGER_LITERAL <AST=INTNode>
;
INTNode class
public abstract class Expr : antlr.BaseAST{
public abstract int value();
}
public class INTNode:Expr{
int val=0;
public INTNode(Token tok){
val=int.Parse(tok.getText());
}
public override int value(){
return val;
}
public override void initialize(AST t){
}
public override void initialize(IToken t){
}
public override void initialize(int i,string s){
}
}
I have just newly downloaded Microsoft Framework 2.0, but the problem is still persisted.
