Cool stuff. Also BaseVisitor is a good thing.
For generic return types this would be in each context class
public <R> R accept(Visitor<R> visitor) {
return visitor.visit(this);
}
and something like this in a visitor implementation provided by the user
public Integer visit(startContext ctx) {
return ctx.e.accept(this);
}
Am I right?
Visitor interface and blank default implementation would be generated by ANTLR I guess.
from antlr4.
The generated visitor interface might look like this
public interface Visitor {
R visit(rule1Context ctx);
R visit(rule2Context ctx);
...
}
from antlr4.
Fixed with parrt/antlr4@725b105. Merged into master in #16.
