| * <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. Unless {@linkplain | |
| * HttpClient##cancel otherwise specified}, 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}. | |
