| * <p> |
| * Nashorn parser API provides interfaces to represent ECMAScript source code |
| * as abstract syntax trees (AST) and Parser to parse ECMAScript source scripts. |
| * </p> |
| * <p> |
| * Using parser API user can write Java code to access parse tree |
| * representation of ECMAScript source. Script source may be a file, |
| * a URL or a String. Unless stated otherwise null argument in methods of this |
| * package result in NullPointerException being thrown. |
| * </p> |
| * |
| * <pre> |
| * <code> |
| * import jdk.nashorn.api.tree.*; |
| * import java.io.File; |
| * |
| * // Simple example that prints warning on 'with' statements |
| * public class Main { |
| * public static void main(String[] args) throws Exception { |
| * // Create a new parser instance |
| * Parser parser = Parser.create(); |
| * File sourceFile = new File(args[0]); |
| * |
| * // Parse given source File using parse method. |
| * // Pass a diagnostic listener to print error messages. |
| * CompilationUnitTree cut = parser.parse(sourceFile, |
| * (d) -> { System.out.println(d); }); |
| * |
| * if (cut != null) { |
| * // call Tree.accept method passing a SimpleTreeVisitor |
| * cut.accept(new SimpleTreeVisitor<Void, Void>() { |

| * public Void visitWith(WithTree wt, Void v) { |
| * // print warning on 'with' statement |
| * System.out.println("Warning: using 'with' statement!"); |
