+ * Nashorn parser API provides interfaces to represent ECMAScript source code + * as abstract syntax trees (AST) and Parser to parse ECMAScript source scripts. + *
+ *+ * 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. + *
