getTypedStringValue() {
    return this.privateDoNotAccessOrElseSafeHtmlWrappedValue_.toString();
  }
Returns this SafeHtml's value as string.

IMPORTANT: In code where it is security relevant that an object's type is
indeed `SafeHtml`, use `SafeHtml.unwrap` instead of
this method. If in doubt, assume that it's security relevant. In
particular, note that goog.html functions which return a goog.html type do
not guarantee that the returned instance is of the right type. For example:

<pre>
var fakeSafeHtml = new String('fake');
fakeSafeHtml.__proto__ = SafeHtml.prototype;
var newSafeHtml = SafeHtml.htmlEscape(fakeSafeHtml);
// newSafeHtml is just an alias for fakeSafeHtml, it's passed through by
// SafeHtml.htmlEscape() as fakeSafeHtml
// instanceof SafeHtml.
</pre>

@return {string}
@see SafeHtml.unwrap
@override
@deprecated Use the native `toString` or the `String` constructor instead.
