/**
* Google-specific implementation of the OAuth 2.0 request to refresh an access token using a
* refresh token as specified in <a href="http://tools.ietf.org/html/rfc6749#section-6">Refreshing
* an Access Token</a>.
*
* <p>Use {@link GoogleCredential} to access protected resources from the resource server using the
* {@link TokenResponse} returned by {@link #execute()}. On error, it will instead throw {@link
* TokenResponseException}.
*
* <p>Sample usage:
*
* <pre>
* static void refreshAccessToken() throws IOException {
* try {
* TokenResponse response =
* new GoogleRefreshTokenRequest(new NetHttpTransport(), new GsonFactory(),
* "tGzv3JOkF0XG5Qx2TlKWIA", "s6BhdRkqt3", "7Fjfp0ZBr1KtDRbnfVdmIw").execute();
* System.out.println("Access token: " + response.getAccessToken());
* } catch (TokenResponseException e) {
* if (e.getDetails() != null) {
* System.err.println("Error: " + e.getDetails().getError());
* if (e.getDetails().getErrorDescription() != null) {
* System.err.println(e.getDetails().getErrorDescription());
* }
* if (e.getDetails().getErrorUri() != null) {
* System.err.println(e.getDetails().getErrorUri());
* }
* } else {
* System.err.println(e.getMessage());
* }
* }
* }
* </pre>
*
* <p>Implementation is not thread-safe.
