* Authorization flow
* For more information about authorization flow, see {@link OAuth2CodeGrantFlow}.
* Client feature
*
* Use method {@link #feature(String)} to build the feature. OAuth2 client filter feature registers
* the support for performing authenticated requests to the
* Service Provider. The feature uses an access token to initialize
* the internal {@link javax.ws.rs.container.ContainerRequestFilter filter}
* which will add {@code Authorization} http header containing OAuth 2 authorization information (based
* on {@code bearer} tokens).
*
*
*
* The internal filter can be controlled by properties put into
* the {@link javax.ws.rs.client.ClientRequestContext client request}
* using {@link javax.ws.rs.client.ClientRequestContext#setProperty(String, Object)} method. The property key
* is defined in this class as a static variables
* ({@link OAuth2ClientSupport#OAUTH2_PROPERTY_ACCESS_TOKEN} (see its javadoc for usage).
* Using the property a specific
* access token can be defined for each request.
*
* Example of using specific access token for one request:
*
* final Response response = client.target("foo").request()
* .property(OAUTH2_PROPERTY_ACCESS_TOKEN, "6ab45ab465e46f54d771a").get();
