Leave is called after children nodes have been visited. The returned node's type can be different from the input node if it is a ExprNode, Non-express

Accept accepts Visitor to visit itself. The returned node should replace original node. ok returns false to stop visiting. Implementation of this met

Myprintf mimics fmt.Fprintf(buf, ...), but limited to Node(%v), Node.Value(%s) and string(%s). It also allows a %a for a value argument, in which case

Enter is called before children nodes are visited. The returned node must be the same type as the input node n. skipChildren returns true means childr

GenByArgs generates a new *Error with the same class and code, and new arguments.

New creates an *Error with an error code and an error message. Usually used to create base *Error.

Walk calls visit on every node. If visit returns true, the underlying nodes are also visited. If it returns an error, walking is interrupted, and the
