* serialization.
* @param {?boolean=} opt_useUnsafeParsing Whether to skip validation before
* evaluating. Safe parsing is very slow on large strings. On the other
* hand, unsafe parsing uses eval() without checking whether the string is
* valid, so it should only be used if you trust the source of the string.
* @constructor
* @implements {goog.json.Processor}
* @final
* @deprecated Use goog.json.NativeJsonProcessor.
