The tree grammar rule below causes the error "syntax error: antlr:
MathTree.g:42:1: unexpected token: @", but I don't understand why.
Polynomial is a Java class in the same package of the classes
generated from the grammar.
Do you see anything syntactically wrong with this?
polynomial returns [Polynomial result]
@scope {
Polynomial currentPolynomial;
}
: ^(POLYNOMIAL term*) {
$result = currentPolynomial = new Polynomial();
}
;
