      28  * Nashorn parser API provides interfaces to represent ECMAScript source code
      29  * as abstract syntax trees (AST) and Parser to parse ECMAScript source scripts.
      30  * </p>
      31  * <p>
      32  * Using parser API user can write Java code to access parse tree
      33  * representation of ECMAScript source. Script source may be a file,
      34  * a URL or a String. Unless stated otherwise null argument in methods of this
      35  * package result in NullPointerException being thrown.
