Methods

accept<E>(AstVisitor<E> visitor) → E?

inherited
findPrevious(Token target) Token?
Returns the token before target, or null if it can't be found.
inherited
getProperty<E>(String name) → E?

inherited
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value.
inherited
thisOrAncestorMatching<E extends AstNode>(bool predicate(AstNode)) → E?
Returns either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there's no such node.
inherited
thisOrAncestorOfType<E extends AstNode>() → E?
Returns either this node or the most immediate ancestor of this node that has the given type, or null if there's no such node.
inherited
