| 53 |     \brief The QAbstractOAuth2 class is the base of all | 
| 54 |     implementations of OAuth 2 authentication methods. | 
| 55 |     \since 5.8 | 
| 56 |  | 
| 57 |     The class defines the basic interface of the OAuth 2 | 
| 58 |     authentication classes. By inheriting this class, you | 
| 59 |     can create custom authentication methods using the OAuth 2 | 
| 60 |     standard for different web services. | 
| 61 |  | 
| 62 |     A description of how OAuth 2 works can be found in: | 
| 63 |     \l {https://tools.ietf.org/html/rfc6749}{The OAuth 2.0 | 
| 64 |     Authorization Framework} |
