| /** |
| * <h2>HTTP Client and WebSocket APIs</h2> |
| * |
| * <p> Provides high-level client interfaces to HTTP (versions 1.1 and 2) and |
| * low-level client interfaces to WebSocket. The main types defined are: |
| * |
| * <ul> |
| * <li>{@link java.net.http.HttpClient}</li> |
| * <li>{@link java.net.http.HttpRequest}</li> |
| * <li>{@link java.net.http.HttpResponse}</li> |
| * <li>{@link java.net.http.WebSocket}</li> |
| * </ul> |
| * |
| * <p> The protocol-specific requirements are defined in the |
| * <a href="https://tools.ietf.org/html/rfc7540">Hypertext Transfer Protocol |
| * Version 2 (HTTP/2)</a>, the <a href="https://tools.ietf.org/html/rfc2616"> |
| * Hypertext Transfer Protocol (HTTP/1.1)</a>, and |
| * <a href="https://tools.ietf.org/html/rfc6455">The WebSocket Protocol</a>. |
| * |
| * <p> In general, asynchronous tasks execute in either the thread invoking |
| * the operation, e.g. {@linkplain HttpClient#send(HttpRequest, BodyHandler) |
| * sending} an HTTP request, or by the threads supplied by the client's {@link |
| * HttpClient#executor() executor}. Dependent tasks, those that are triggered by |
| * returned CompletionStages or CompletableFutures, that do not explicitly |
| * specify an executor, execute in the same {@link |
| * CompletableFuture#defaultExecutor() default executor} as that of {@code |
| * CompletableFuture}, or the invoking thread if the operation completes before |
| * the dependent task is registered. |
| * |
| * <p> {@code CompletableFuture}s returned by this API will throw {@link |
| * UnsupportedOperationException} for their {@link |
| * CompletableFuture#obtrudeValue(Object) obtrudeValue} |
| * and {@link CompletableFuture#obtrudeException(Throwable) |
| * obtrudeException} methods. Invoking the {@link CompletableFuture#cancel |
| * cancel} method on a {@code CompletableFuture} returned by this API may not |
| * interrupt the underlying operation, but may be useful to complete, |
| * exceptionally, dependent stages that have not already completed. |
| * |
| * <p> Unless otherwise stated, {@code null} parameter values will cause methods |
| * of all classes in this package to throw {@code NullPointerException}. |
| * |
| * @since 11 |
