Class MinimalH2AsyncClient

java.lang.Object

org.apache.hc.client5.http.impl.async.CloseableHttpAsyncClient

org.apache.hc.client5.http.impl.async.MinimalH2AsyncClient

All Implemented Interfaces:

Closeable, AutoCloseable, HttpAsyncClient

@Contract(threading=SAFE_CONDITIONAL)
public final class MinimalH2AsyncClient
extends CloseableHttpAsyncClient

Minimal implementation of HTTP/2 only CloseableHttpAsyncClient. This client is optimized for HTTP/2 multiplexing message transport and does not support advanced HTTP protocol functionality such as request execution via a proxy, state management, authentication and request redirects.

Concurrent message exchanges with the same connection route executed by this client will get automatically multiplexed over a single physical HTTP/2 connection.

Since:

5.0

                    org.apache.hc.core5.concurrent.FutureCallback<T> callback)

Description copied from interface: HttpAsyncClient

Initiates asynchronous HTTP request execution using the given context.

The request producer passed to this method will be used to generate a request message and stream out its content without buffering it in memory. The response consumer passed to this method will be used to process a response message without buffering its content in memory.

Please note it may be unsafe to interact with the context instance while the request is still being executed.

Type Parameters:

T - the result type of request execution.

Parameters:

requestProducer - request producer callback.

responseConsumer - response consumer callback.

pushHandlerFactory - the push handler factory. Optional and may be null.

context - HTTP context. Optional and may be null.

callback - future callback. Optional and may be null.

Returns:

future representing pending completion of the operation.
