Function Walk

pkg/sql/ast/visitor.go:161–183

Walk traverses an AST in depth-first order using the visitor pattern. Walk performs a depth-first traversal of the Abstract Syntax Tree starting from the given node. It uses the Visitor interface to allow custom processing at each node. Traversal Algorithm: 1. Call v.Visit(node) for the current no

(v Visitor, node Node)

//
// See also: Inspect(), Visitor, Inspector
func Walk(v Visitor, node Node) error {
	if node == nil {
		return nil
	}

	visitor, err := v.Visit(node)
	if err != nil {
		return err
	}

	if visitor == nil {
		return nil
	}

	for _, child := range node.Children() {
		if err := Walk(visitor, child); err != nil {
			return err
		}
	}

	_, err = visitor.Visit(nil)
	return err
}

// Inspector represents a function-based AST visitor for simplified traversal.
