Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
inherited
findPrevious(Token target) Token?
Return the token before target or null if it cannot be found.
inherited
getProperty<E>(String name) → E?
Return the value of the property with the given name, or null if this node does not have a property with the given name.
