Hi Victor,
Define a class LinearExpr like this:
package foo;
public class LinearExpr {
// ... the rest of your class...
}
and in your grammar, import that class like this:
grammar LinearExpression;
@header {
import foo.LinearExpression;
}
// ... the rest of your grammar ...
@header will automatically put everything you define in there at the start
of your parser class. It does the same as:
@parser::header {
import foo.LinearExpression;
}
// ... the rest of your grammar ...
If you want your lexer and parser to be in the same package, say foo.parse for
example, do something like this:
grammar LinearExpression;
@parser::header {
package foo.parse;
import foo.LinearExpression;
}
@lexer::header {
package foo.parse;
import foo.LinearExpression;
}
// ... the rest of your grammar ...
Regards,
Bart.
